Systemd and nssswitch/LDAP problem (5min boot) - drives me crazy

Since I've migrated to systemd my systems needs 5 minute to boot.

It seems stuff from systemd-binfmt.service and systemd-tmpfiles-setup.service is not able to play with my nss_ldap config. With the default nsswitch.conf booting is as fast as expected.
$ cat /etc/nsswitch.conf
# Begin /etc/nsswitch.conf
#passwd: files
#group: files
#shadow: files
passwd: files ldap
group: files ldap
shadow: files ldap
publickey: files
hosts: files dns myhostname
networks: files
protocols: files
services: files
ethers: files
rpc: files ldap
netgroup: ldap [NOTFOUND=return] files
# End /etc/nsswitch.conf
I think those "services" do some uid / guid lookups which ends with NOT reaching the LDAP server due to no network at this stage. I tried to put the netconfig earlier in the boot but i went into troubles like
systemd[1]: Walked on cycle path to [email protected]/start
Any idea how to fix this issue ?

I found a workaround
I get Network early available with the following steps
Installed mkinitcpio-nfs-utils
Modified the /etc/mkinitcpio.conf
Added the module for the networkcard
MODULES="atl1c"
Added "net" to the HOOKS
HOOKS="base udev autodetect pata scsi sata filesystems usbinput fsck net"
Run mkinitcpio -p linux
Added kernel parameter ip
kernel /boot/vmlinuz-linux ip=:::::eth0:dhcp root=/dev/sda1 ro init=/usr/lib/systemd/systemd

System set-up with two drives (and one used as a boot drive)

Apologies if this has been asked before; I have searched a little for this info, but couldn't really find it.
I'm looking ahead to the glorious day when I eventually get my dream killer system, i.e. a Powermac (or whatever it's called when it goes Intel) with all the trimmings.
I like the idea of having something like a WD Raptor as a boot drive, with a large second drive mainly for storage plus the obligatory external FW drive for back-up.
I know from using Windows that a using a boot drive (or partition) with everything else on another volume is ok, but I had read/heard (perhaps incorrectly) that OS X likes/needs (particularly for iLife) to keep Apps in the Applications folder, music in the music folder etc.
So what would be the best way of achieving this type of set-up on the Mac?
Thanks in advance.

iTunes doesn't care where the music is stored. Just make sure it's NOT set to "Copy files to iTunes Music folder when adding to library" in the iTunes preferences (under the advanced tab.
iPhoto 5 and earlier is a bit more picky. iPhoto 6 has an option very similar to iTunes that allows you to store your music wherever you want, without it automatically copying to the iPhoto folder. If you get a new PowerMac, it will contain the latest version of iPhoto, so you don't have to worry about it.
I never use the other iLife apps, so I don't have an answer for those.

Systemd and LUKS password decryption on boot

Hello!
Today I changed over to systemd with my Arch Linux desktop PC. All went fine, but there is one problem where I can't find a solution for. I have two LUKS-encrypted devices in my system, where the password should be asked for on boot. This works, also with systemd, but on my screen, the prompting text first appears, then systemd outputs some other status messages and then seems to wait for the password. This often yields in problems entering the password because I'm not sure where to enter it now. This is how my screen looks like. I marked the positions with the prompt and the associated passwords. As you see, typing the second password yields in an error, but I'm sure I did enter the correct one.

Any idea how to fix this ugly look for the password boot prompt?
Thanks

I hate to bump this for a non-solution-providing post, but I've been starting a truecrypt mounting service manually for a long time as I've not figured out how to do it at boot. Would you be kind enough to post your .service file?
Mine is currently:
ExecStart=/bin/sh -c '/usr/bin/truecrypt -t --protect-hidden=no -k "" --filesystem=none --slot=1 -p `systemd-ask-password "Enter password for truecrypt volume: "` /dev/sda4'
This doesn't seem to work at boot and the systemd-ask-password bit gets ignored during the boot process. I'd love to get this solved to save typing it manually time I boot.
Thanks!

HT204349 My iMac 2011 with Snow leopard and Bootcamp has problem since yesterday. Its boot up time is about 8minutes now and has very slow response once it boot up. please help me!

This problem just started yesterday.

CCC, TimeMachine and SD need a whole drive to themselves as they copy everything, including OS X and all your programs etc.
Right now you don't need that as your having a drive issue.
Just copy your user data folders to a external drive that has enough room to hold them.
as you can see I have two user accounts
If your on 10.7 you may have to use the Finder > Go > Computer and then click on your boot drive on the left, then click on Users folder to open it like so to copy those user account folders.
Once those folders are copied to a external drive and the drive is unmounted and removed, you can breath easier.

Be careful with App Store and multiple boot drives.

I just had a strange thing occur. I was fighting with a Messages server problem as described here : https://discussions.apple.com/thread/4322859?start=0&tstart=0 and was alternating back and forth between an upgraded boot drive, where Messages was not working, and a fully functioning backup boot drive. Two physically separate disks on the same system.
A solution to the problem above was to manually delete Server.app from the boot drive, reboot, and reinstall Server.app from App Store.
Working on the non working (Messages Server) upgraded drive which was the boot disk, I removed Server.app and rebooted. There is now no Server.app on this drive.
Log in to App Store and ask for install of Server software. Did not receive a drive selection request. Assumed install would be on boot disk.
Reboot.
App Store had upgraded my backup drive to the new Server.app. The boot drive still did not have Server.app on it.
I now have no backup.
Be careful.

The issue seems not only for TweetDeck but also for other applications and functions. For example, I tried to buy and install the following Mac app, but actually nothing happened after I clicked the BUY APP button.

C: hard drive (boot drive) for dowloading and installing files

Hi, I do not want Adobe Creative Cloud to be installed on my C: hard drive.
I thought that setting up the install drive in Creative Cloud would fix the pb for the apps I want to install, but:
the Creative Cloud software itself is installed on C:
the apps are installed on C:
and the download location off the apps that is used to download and dezip the files before the app is installed.
Does anyone can tell me how to solve this (HUGE) problem: my boot drive is a small SSD and I would rather not use it for temp files and non system software.
Thank you for your answers.

Hi Paul,
Should I use a utility for copying files? or just the finder.d
Finner won't work, Best way to get an exact bootable copy of your old drive to the new one is with Carbon Copy Cloner...

Have you Formatted the new Drive yet?

Using external hard drive as both a boot drive and time machine backup

My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment.
I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,
Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine
Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and
one for Time Machine. But is there any way to add a partition without erasing the existing one with
Time Machine only on it?
Sorry if line breaks here are weird. Doing this from iPhone.

Neil , I have a mid 2010 27" imac running 10.6.8 and i want to install Lion , when i purchase Lion from app store will it give me any install options as I would like to be able to dual boot using SL and Lion , I have 500 gigs left on my 1 tb drive (should I do this) or would I be better of using an external bootable drive as I also want to use Ubuntu and or Linux down the line.
Any and all support , help and advice will be appreciated.
If you would like to e-mail me you can find it on my profile page.

SSD Boot Drive for Mac Pro

Apologies in advance, I’m really not great with this sort ofstuff.
Basically, what I would like to do is add an SSD to my MacPro and use that as my boot drive. Ihave a 1TB HDD which is currently doing everything but I’d like to use thispurely to store music, videos etc.
As well as booting to Lion, I’d also like to use the SSD torun Windows 7 with VMware Fusion – presume this doesn’t cause any problems?
The plan would be to have the system software andapplications on the SSD and everything else on the HDD. Only thing I’m not sure of is where the homedirectory should go?
Does this all sound like a realistic goal? Also, will this be an relatively straightforward process? Migration Assistant?
Thanks.

So in effect, lets just say your SSD drive fails. As you are currently setup, can you boot from your secondary drive to your backed up OSX, or do you have to have restore that backup image to a new hard drive?
My whole rational of keeping the home dir separate (disk) from the boot dir is that I can switch among any number of boot drives any time I want to. For example, as a hypothetical case*, I use 10.6.5, and I want to update to 10.6.6, 10.6.7, or 10.6.8, I just do it to my ssd. Now I can still boot from my 10.6.5 backup, say for the sake of comparison to some weird behavior I see on the update, without a blink of the eye. I'm still using my same (common) home dir because it is not involved with the update. If I want to go "back" I can restore the ssd from my 10.6.5 backup.
Of course I would actually do it the other way and boot and update from the backup leaving the ssd alone (don't want to write to it any more than I have to). Only if I was satisfied with the new OS on the backup would I then update my ssd.
The point of all this is keeping the home dir off the boot dir allows you to "flit", "jump", switch, whatever, to different OSs (or backups of the same OS) at will. Your home dir is none the wiser unless the OS dramatically changes or screws things up (so that's why this technique may or may not work across major OS revisions -- Snow Leopard to Lion for example, but its great with a single OS sequence).
While everyone always debates the pros and cons of keeping the home dir separate from the boot dir, what always seems to get lost or not mentioned is the benefit of being able to switch among the OSs when they are separate.
So all of this was a long way of answering your question -- no you don't have to backup to the original boot drive before using it. Just boot from the backup. Your home dir couldn't care less.
* For me going to 10.6.6, .7., .8 is hypothetical since I use 10.6.5 and have no current plans of updating beyond that (can you say "app store"? -- don't want it my machine -- and I won't debate any comments on this -- its my personal decision. And besides this is off topic.).

Yoga 13 Supports 500gb Boot drive but not running as SATA III?

Hi All,
I had previously installed a 250gb Plextor drive in the second mSata slot and upgraded the RAM to 8gb in my Yoga 13 IdeaPad which I purchased early in 2013. I followed the installation instructions and guidance offered by the Community so thanks to all who posted and other than the occasional skipped heartbeat as I removed cables it went well.
As SSD prices are now dropping I decided to try adding a Samsung 840 EVO 500gb. I was a little skeptical about taking the chance after reading the comments posted here and elswhere regarding the 256gb "ceiling" for both slots but decided "no pain, no gain" and went ahead anyhow.
I'm happy to report ( I think) that I was able to install the drive. First, in the secondary slot and then finally, as the boot drive in the primary slot. I had originally installed it in the 2nd slot after removing the Plextor drive and leaving the original 128gb boot in place. I entered the bios and it was recognized, I saved the settings and then initialized and formatted the drive with the disk management tool. No problems.
I then wanted to move the Plextor drive to the primary so that I would have a larger boot drive. Since the old primary was a Samsung I though I might be able to use the Samsung migration utility to clone the old boot drive to the Plextor. Following suggestions from others I put the Plextor into slot one and then put the old boot drive into an external usb3 housing. I tried several times to boot from the old boot drive through the usb but couldn't get it to work so I reinstalled the old boot drive back into slot 1.
Just for kicks I ran the migration utility with the Plextor attached though the usb. It didn't recognize the plextor drive but it did offer the option to clone to the 500gb in the second slot. I figured I had nothing to lose so I went for it. The clone finsihed and I then swapped the 500 gb into slot 1, put the plextor back into slot 2, started the bios, verified the drives were present and that the 500gb was the boot, and saved the changes. Presto, it booted just fine and everything appears to be ok. However...
Went I started the Samsung performance tool it told me that my drive was not connected to a sata III controller. The performance benchmark would back that up as my read/write and iops performance are pretty poor compared to what I was hoping. I've confirmed that the Intel C216 chipset that is installed does indeed support sata III 6gbs rates but the drive doesn't seem to think so.
There doesn't appear to be anything posted on the board about the controller or any similar issue - can anyone offer some guidance?
Thanks,
Paul

Well dont worry as to whether the Tranfer Mode is Reporting you S-ATA Drive at, as the UDMA Modes do NOT apply to S-ATA Drives, so if it is Reporting UDMA-5 or UDMA-6, there is No Difference with the Transfer speeds as far as S-ATA Drives are concerned........And I would Try to Enable the RAID Option in the BIOS, If indeed you are running a RAID Array ...............Sean REILLY875

Buying a new iMac - can you use an external SSD drive as boot drive?

Here is the question: Can you attach an external SSD and use that as your boot drive accompanying an iMac? This way all the Apple warranties stay valid but I am not saddled with the expense of the Apple installed SSD price?
Now for some background ...
I am looking to buy a new iMac replacing my loved but woefully underpowered Mac Mini. In a perfect world I would like the following set-up based on how today's iMacs can be configured:
Processor: 3.4GHz Quad-Core Intel Core i7
Memory: 16GB 1333MHz DDR3 SDRAM - 4x4GB
Hard Drive: 1TB Serial ATA Drive + 256GB Solid State Drive
Graphics: AMD Radeon HD 6970M 2GB GDDR5
Optical Drive: 8x double-layer SuperDrive
The problem is I'd rather not spend $3200+. I would imagine most people plug something similar in and then begin to ID must vs. nice to haves. So, here are my must haves:
Memory: Minimum 16GB 1333MHz DDR3 SDRAM - 4x4GB (I was thinking of starting with minimum and then purchase the right RAM and installing myself)
Graphics: AMD Radeon HD 1GB
Hard Drive: 256GB Solid State Drive
I like to work the graphics side and have a media library of almost 1TB (uploading, downloading, converting, editing, etc.). With my existing setup I have 3+TB of external storage but again, am suffering massively in the horsepower department as it takes hours for me to do what I believe a new iMac can help me accomplish in a fraction of that time. This is not my profession so while I looked at the towers I still need this computer to serve as a family computer as well. Appreciate your thoughts and feedback.
Cheers,
-Jim

Ok this is great as we are progressing through.
So yes it can be done but there's the caveat of the "pipes" once you go external. The only option for an external SSD Drive with thunderbolt that I know of is LaCie's 240 GB version ... Priced at $800.
I think what I will need to do is suck it up. The new MacBooks have the core technology I'd like but we really want the larger screen.
Last question - should I wait/when might we expect an updated line of iMacs? In a few months or not for a while? That answer may provide some direction if it is anticipated to be sooner vs later.
Thank you!

Boot Drive fills on it's own...?

So start of another school year...build and test images, blah, blah, blah. Everything running great. After all machines were imaged I notice server is responding slow. Log on through ARD and i'm met with a warning message that HD is almost full (4mb remaining!). Its a small boot partition so I think maybe I made it too small (though I've had no issues the past few years). Install new drive with larger partition and clone. Reboot and everything is good. Today after the weekend I come in and see that the new boot drive has filled itself as well. Right now NO ONE is using or accessing the drives as I haven't enrolled the kiddos yet. So it's happening on it's own accord. I'm sure the clone just copied whatever originally caused the problem, and it just took longer to fill the much larger drive.
Suggestions?

No cause found yet. Has happened twice so far for me....even put in new HD to give it "room". Here's an interesting artifact that someone may be able to run with:
Last time it happened I started it up in FW mode on another machine. Finder verifies that drive is full. No Logs of abnormal size, no mystery folder of GB unaccounted for...major frustration. Decide I'll boot normally and let it run dog slow so I can check console out. Guess what? It booted fine and reported back with 60GB of free space! My first thought that maybe the swap file wasn't clearing itself but surely booting into FWDM would have forced clear it. Long story short, I'm keeping an eye on the HD storage levels...been holding strong for a week now. If it happens again, maybe try just rebooting machine....

Express Card 34 Boot Drive?

I have been hearing about these new ssd's incredible performance and looked into getting one. only problem is if you want a decent capacity, you pay hundreds. So I was wondering, could you get like a 32gb flash memory express card 34 and use it as a boot drive and use your original hdd for storage? If so that would be great. Does anyone know?

John-F,
What do you mean you tried to update the OS while the drive was in the Express Card Slot and the update appears to have completed? Which update specifically? Also, the OS update doesn't help you when you're trying to boot from it because it's not recognized in the BIOS; at least my BIOS. I have a Lenovo U110 and was able to clone the OEM drive after using Paragon Partition Manager Magic 9.0 and Drive Clone. Unfortunately my OEM drive are bigger than my SSD, therefore I had to move all the files off my OEM drive except for the Windows 7 install which brought the OEM size below the size of the ExpressCard SSD. Once I did that, I could successfully clone the OEM drive. However, upon boot up to the new SSD cloned drive, it failed on the boot manager missing bootmgr files. I also have a RunCore SSD that's a 64GB 1.8" PATA Zif that just arrived Friday and I've been trying to get it to work as well. Neither drive says Windows can be installed to each respective disk because "the computer's hardware may not support booting to this disk". I don't believe this is a BIOS issue because there isn't a BIOS update to the U110 so I'm not sure how cloning the drive helps in this situation because if it can't be recognized during a Windows install, how's it going to be recognized post clone and first boot up? That just doesn't make sense to me, but I've seen stranger things happen with technology.
Any ideas here? My end goal is to use the RunCore SSD 1.8" Zif as my primary drive, and the 48GB FileMate SolidGO ExpressCard Ultra SSD as a secondary mainly Read drive so that I can maintain the 115MB/sec throughput as much as possible.
Thanks in advance,
Jason Volpe

My opinion on WD Raptor as boot drive

After doing much research, I decided to buy the WD 150 ADFD and use it as a boot drive in my MacPro 2.66. In the other drive bays, I have two WD RE320's as RAID 0, and a single WD 500 for storage.
The reason I'm posting is not to specifically ask a question, but to give my honest opinion on whether a single Raptor makes for a good boot drive or not. As I did my research on the web, I found the general consensus that the Raptor was the drive to buy if you could afford it. The noise was supposed to be not that noticiable, and the speed vs lack of storage was a reasonable trade-off. It's supposed to be the premium SATA drive! As it turns out, I found that consensus to be wrong, and my trust in others opinions is going to cost me a 15% restocking fee. I bought a Raptor last week and have been trying it out over the holidays. I'm sending it back tomorrow and eating the restocking fee that Newegg charges for returns.
The reason I'm returning the drive is because, first off, the speed is not that significant when you consider the premium you are paying for it. The Raptor shaved about 3 seconds off my boot time. Big deal (sarcasm). Applications open maybe a second or two faster (big deal again), though it's hard to tell on my MacPro because it's so fast to begin with. As for general "snappiness" to the OS and general computing, I found NO discernable difference between the Raptor and the stock Seagate that shipped with the computer. Working with Final Cut Pro, I didn't notice any difference in performance and that is my primary application. The RAID 0 is probably having more positive effect on rendering than the Raptor. Then there is the noise... first let me say that the Raptor is quiet when it's at idle. I have no issue with that. The problem for me is that when the head starts seeking, the sound is jarring. Like microwave popcorn? Tadadadadadada...tick....tick....tick....tadadadadada.
What makes the seek noise so bad is that the computer is normally so quiet by comparison. So, if I'm sitting in my office and it's really quiet, all I hear is the faint sound of my X1900 fan. Then the Raptor kicks in and it's like finger nails going across a chalk board. Okay... maybe that an exaggeration, but it really is distracting! I also really hate when the Raptor just does a random loud click when your surfing the web or not doing anything disk intensive. Like, as I'm writing this post... click.......(silence)................... click, click...............(silence)... you get the idea. None of my other drives do that.
I think the Raptor is probably the way to go if your using them in a Raid configuration AND in an area with fairly loud ambient sound, or if you have a tendency to always have music on. However, if you are fairly sensitive to jarring noise and don't need to worry about shaving a few seconds off boot times, then I suggest to go with something besides the single Raptor as boot. Raptors in RAID is another issue entirely and I'm not knocking that. What I am knocking is when I read where someone posts that the noise in their Raptors in RAID are barely noticable. I call BS on that so beware.
I'm sending my Raptor back soon as I get an RMA and going back to the stock Seagate until I figure out what else to use. Maybe the WD SE 320 Caviar or the Maxline Pro? Something around 320GB for OS and applications only and a Windows partition.
Any suggestions?
Thanks for reading. Your comments are appreciated!
Al

To be honest, I haven't run extensive scientific
tests but the ones I did perform didn't show much of
an advantage using a single Raptor as the
OS/application boot drive. Last night I booted off
the Raptor and then loaded a Final Cut project and
rendered out the timeline. The scratch disk was set
to the RAID and the media was coming off a storage
drive. It took 4 minutes 49 seconds to render the
timeline. Next, I booted off the stock Seagate 160
(7200.09) and ran the same render. The OS was an
exact same version that I'm running on the Raptor (I
had cloned the Seagate from the Raptor using
SuperDuper!). Anyway, I ran the render on the same
file and it took exactly the same amount of time. 4
minutes 49 seconds.
Again, am I missing something here?
You are not missing anything.
Using a "fast disk" as the system drive will improve some things, and if you are used to an older, slower disk drive then you'll probably notice a bigger difference. A Raptor in a macpro for OS use is only going to help marginally, in the way you have noted. Better, but not that much.
I'm not sure about your expectation of seeing FCP perform better in your test though. I wouldn't expect there to be any improvement there. Rendering speed tends to be limited by processing rather than disk speed for a start. Where a fast drive helps is when applications need fast reads and writes. Writing a 100GB self-contained movie from the FCP timeline to some external storage wont be speeded up no matter what system drive you have (unless the original footage is stored on the OS disk of course!). The speed will be dictated by the drive your writing to and the drive you are reading from. Unless you have set your scratch disk as your boot drive or footage is stored there or you're writing to it then the boot drive will have no effect.
Like everything in computer land, whether you need that extra power, speed, size etc always erm... "depends". having just 5% extra kick might be the difference between a realtime preview or a render for eg.
I agree with a "vibe" I am picking up from you though: that all those reviews and user comments on the web can be very misleading. If you've spent $50 more on something then its not easy to admit (even to yourself) that it wasn't ~really~ worth it. Once you see the quoted benchmarks for yourself and the 2sec reduction at boot most folks will feel the purchase was worth it. Will it make you work better? Not really. I went from a G3 B/W mac to a MacPro but the music I make is no more jolly than it was before
If you ~really~ want to see big improvements to any standard drive you have to look at RAID and more specialist solutions like scsi and fibre channel - but even these wont make your processor work any quicker!

Can I just move the boot drive from my iMac to new Quad G5?

I've "upgraded" from a 1.8 GHz 20" iMac (Rev. A) with 2 GB RAM to a 2.7 GHz Quad G5 with 5 GB RAM and I'm not seeing the performance jump I expected for simple stuff like logging in after system restart (and the start up applications), launching applications, etc. The system profiler reports 4 CPUs, 5 GB RAM, etc. Memory intensive operations seem quicker but I haven't performed any real benchmarks and have a new drive in the iMac. The system just doesn't "feel" faster for basic stuff. I realize these may not be CPU intensive tasks but still expected to see a little more livelier system.
I moved the iMac drive to bay B of the Quad and set it as the boot drive. Are there any folders, caches, etc. that need to be cleared?
The new boot drive (my iMac's old drive) is a 300 GB Seagate ST3300831AS. (The original iMac drive developed a problem and was replaced with this drive a couple of months ago. I noticed an improvement as this drive is a little faster than the stock Maxtor.)
The original Quad drive is a 500 GB Hitachi HDS725050KLA360.
Specs of the two drives seem to be virtually identical as far as I can tell. (Actually I think the Seagate has .5 ms faster seek.)
I'm thinking the issue is that the lack of performance gain I'm seeing is disk I/O and that the iMac wasn't lacking in power for basic stuff so I will only see the performance gain with applications that can take advantage of the additional CPUs and/or GPU. Still, I expected the system to feel a little faster.
I just tried Virtual PC and it didn't seem to start up much faster and I definately expected to see a big improvement with this application.
Any ideas?

That's correct, I moved the iMac drive to the second bay in the new Quad G5.
I wasn't sure if any combination of events would fix this. I didn't think there were any caches or anything else I needed to clear but just posted here to be sure.
The iMac was 10.4.3 and current with all updates. I didn't really think anything was missing but posted here to be sure. My understanding of Mac OS X is such that I was pretty sure that everything the Quad needed was already on the iMac drive. Not that this is necessarily any more reliable, but I asked at the Apple store and they said there was no problem with me moving the drive to the Quad and setting it as the startup volume.
A few people have told me that it's probably OK, but the official method is to use the migration assistant. So today I installed from the Power Mac OS X discs (10.4.2) to the Hitachi drive which I erased, then ran the migration assistant, then software update, then cloned the Hitachi drive back to the Seagate. I think the performace of the two drives is nearly identical (Seagate ST3300831AS, Hitachi HDS725050KLA360) and wanted the smaller (300 GB) Seagate drive to be my main drive.
I've been using Macs for only about a year and have found the experience interesting. On the plus side the performance is fairly consistant and I don't experience progressive system slowdown over a period of months. And of course there are the system update, viruses, etc. issues which are better. On the negative side basic stuff feels faster on a Windows system. I'll try Photoshop which I have no doubt will be faster on the Quad than the iMac and probably faster than a PC, too. But Safari or Firefox don't feel as fast as IE on a new Windows PC. Just my observation. I invested a lot in this Quad and expected to feel a significant speed boost even if it's only for launching applications and displaying web pages. (I have Comcast's highest speed Internet service.)

Systemd and nssswitch/LDAP problem (5min boot) - drives me crazy
