[Solved] NFS export at boot and net-auto-wired

Hello Guys,
I have a problem with my fileserver. Previously dhcp was enabled through systemctl enable dhcpd@eth0 and everything worked fine. I changed the network to be configured using net-auto-wired, because it seemed a reasonable thing to do and because it allows for a fallback-ip-address in case dhcp fails. Now the problem is that many daemons are (at boot) started before the net is up and so don't work properly, especially nfsd, because exportfs can't resolve the names of the allowed client computers.

For future reference:
net-auto-wired doesn't Wants=network.target at any time (neither when started nor when a connection is made) as does dhcpcd.service (so indeed i had the same problem already before i switched to net-auto-wired but i guess i didn't notice it). now i'm using netcfg.service which actually Wants=network.target and starts Before=network.target so everything works fine. The only thing that is missing is a fallback static ip in case the dhcp does not respond, but that is another question so i will mark this solved.

Ypbind, systemd and net-auto-wired problems

I have the following problem after boot:
YPBINDPROC_DOMAIN: Domain not bound
And can't login with any user!
I have to restart the ypbind so I can login.
I am using systemd and net-auto-wired.service to start my connection.
I think the problem is that the ypbind.service is being started before the network.
# journalctl | grep ypbind
Feb 10 14:36:00 qomplex000 ypbind[369]: Host name lookup failure
I can't find the problem, tried all kinds of configurations on
/usr/lib/systemd/system/ypbind.service
And no change.
I think there is a relation with this:
https://bugzilla.redhat.com/show_bug.cgi?id=632620

oangelo wrote:One can use the words "before" and "after", on *.sevice files, to make sure that the service will start on the right order.
But this does check only start but not completion of the started service. In our case dns is started and systemd moves on, not waiting for a valid dns configuration (but it takes a few seconds for dhcpd to put the nameserver in /etc/resolv.conf). The ypbind service gets started and tries to resolve a dns for ypserver from /var/yp.conf. Since the nameserver is not configured properly at this moment it gets no valid answer. Unfortunately ypbind seems not to be smart enough to retry ypserver and hangs. Thats the cause for 'YPBINDPROC_DOMAIN: Domain not bound'.
From the ypbind manpage:
This ypbind version listens for DBUS messages from NetworkManager. If no NetworkManager is running at startup, ypbind will behave as usual and assumes there is a working network connection. If NetworkManager is running on the system, ypbind will only search and provide NIS informations, if NetworkManager tells that a network connection is available. If NetworkManager establishes a connection, ypbind will reread all configuration files, registers at the local portmapper and try to search NIS servers. If NetworkManager drops a connection, ypbind will unregister from portmapper.
I don't use NetworkManager on these systems (because of keeping it simple, as a real archer).

[Solved] net-auto-wired and ifplugd failing to work

Having installed Arch successfully on one machine I then move to another, so I've just got a fresh install with nothing else.
Using netcfg and ifplugd to manage network interfaces (trying to, did same process and it worked okay on other computer), however systemctl status of net-wired-auto gives:

I can use dhcpcd service and it works fine - but it would be nice to use ifplugd/netcfg.
Not really sure what else to try...
Thanks.

I think you may need to also put a config file into /etc/network.d/ - you can copy one of the sample files there and adapt it to your situation.
Also you have to set the correct interface in /etc/ifplugd/ifplugd.conf
You will also need:
systemctl start net-auto-wired
systemctl enable net-auto-wired
Hope this helps.

[solved] ifplugd; systemd, net-auto-wired: annoying beep

Hello everyone!
I experience annoying pc speaker beeps whenever the net-auto-wired service is getting started or stopped, e.g. on every boot or shutdown.
I've already tried various ways to mute the pc speaker:
"xset -b" in ~/.xinitrc
blacklisting pcspkr module
"setterm -blength 0" in /etc/profile
It doesn't work.
The following log corresponds to stopping and then re-starting the net-auto-wired service after having booted the system.

@sie: thank you very much! This is it! Silence, finally!
But instead of editing the .service file changing the ifplugd configuration is better IMHO. Otherwise the change won't survive an upgrade of netcfg. So I edited /etc/ifplugd/ifplugd.conf and added the "-b" flag to ARGS.
EDIT: I just realized that adding "-b" to the default ARGS of ifplugd does not have the desired effect, the problem persists. So why is this the case? Do the flags which are employed in the .service file bypass the default ifplugd configuration? Or is this my very own user misconception? I did RTFM, though...
Currently this is my /usr/lib/systemd/system/net-auto-wired.service:
[Unit]
Description=Provides automatic netcfg wired connection
[Service]
EnvironmentFile=/etc/conf.d/netcfg
ExecStart=/usr/bin/ifplugd -i $WIRED_INTERFACE -r /etc/ifplugd/netcfg.action -fIns -b
ExecStop=/usr/bin/netcfg iface-down $WIRED_INTERFACE
[Install]
WantedBy=multi-user.target
If this issue really has to be addressed in the .service file, we should file a bug report/feature request.

[Solved] Problems with net-auto-wired, no interent after install

*Background*
I am returning to Arch Linux after being away for about a year. I have finally had a chance to install Arch on my new laptop. Since I am new to systemd and the new installation process I followed the beginners guide very closely.
*Description of the Steps I followed and the Error I encountered*
When I came the the "Configure the Network" Portion of the Beginners' Guide, I chose to follow the net-auto-wired setup. This was partly because I found the warning to be confusing and could not understand why the Guide included a command that "won't work". Additionally I the "net-auto-wired" method seemed given the language of the Guide to be the superior alternative. So I followed the following steps:
# pacman -S ifplugd
# cd /etc/network.d
# ln -s examples/ethernet-dhcp .
# systemctl enable net-auto-wired.service
These commands returned no errors, nor did the net-auto-wired daemon fail to initialize on reboot. I simply did not have a connection with the internet, even after confirming that all the wires were securely plugged in.
*Question for the Forum*
I was able to establish a connection with via several means as well I will likely be installing dbus and wicd to manage my internet connections. So my question is less about how to get connected and more (a) how to trouble shoot net-auto-wired and (b) what language and procedures can we change to the Beginners' Guide so that this issue is not encountered by beginners in the future.
*Information I have Uncovered*
When the net-auto-wired daemon failed to establish a connection. I immediately tried running the following command:
# systemctl enable [email protected]
The output of this command (what is following) showed me what the warning was talking about, how it rename the symbolic link to eth0.service and not enp4s0f2.service as it should have.
ln -s '/usr/lib/systemd/system/[email protected]' '/etc/systemd/system/multi-user.target.wants/[email protected]'
I attempted to resolve this issue by creating the symbolic link with the following command
# ln -s /usr/lib/systemd/system/[email protected] /etc/systemd/system/multi-user.target.wants/[email protected]
After reboot, the appropriately started the dhcpcd@ deamon and established an internet connection.
It also hit me that the netcfg profile "ethernet-dhcp" would be pointing to the wrong interface. I edited the profile to interface with the enp4s0f2 not eth0 and was able to establish a connection manually with the following command but net-auto-wired still failed to work.
# netcfg ethernet-dhcp
At this point I checked the status of the of the net-auto-wired daemon with the following command which uncovered what is most certainly the issue.
# systemctl status net-auto-wired

Obviously the issues with this are it use of eth0 and not enp4s0f2.
I do not know where to go from here but I am curious if the issue of dhcpcd@ misnaming the symlink is some how related to this issue.
Thanks for all your insight and responses.

Yes, it seems that after a period of inactivity (5 minutes ?) the forum software automatically logs someone out.
After that happened to me for the zillionth time, i installed the firefox addon ReloadEvery .
Now i always open 2 tabs for arch forums : 1 that just shows the index, and has reloadevery enabled with a time of 1 minute.
The 2nd tab is for reading/answering etc.
Haven't been logged out automatically since.

i guess this is because ifconfig already has an ip set up?
after that, there is:

guessing this is netctl trying to start up the profile after reboot..
in my rc.conf i have my old settings for eth
i tried to disable the old ip link lines, and rebooted with netctl service active but no ip is being set with ifconfig

Net-auto-wireless isn't really doing anything

I've got netcfg installed and I'm trying to use it for my wifi configuration on my laptop which has an ath9k wireless chip.
I've got my profiles (WPA personal) setup just fine, when I do netcfg my.profile.name it brings it up and it works. However if my wireless drops for whatever reason, or I come to work, I always have to manually do "netcfg profile".
In my rc.conf I have nothing in INTERFACES (only have wlan0 on this machine), I have WIRELESS_INTERFACE defined as wlan0, I have two profiles in NETWORKS, and I have "syslog-ng hal net-auto-wireless netfs crond" in my DAEMONS list.
Can anyone see anything that I'm doing wrong? How does net-auto-wireless actually work?

Okay I can't get it to automatically connect neither to wired no wireless network.
ifplugd at least is trying to connect to networks, I can see in /var/log/everything that but wpa_actiond simply sits there silently and does nothing.
When run manually, either via rc.d/net-auto-wireless or directly, it connects to a wireless access point immediately. No problem here.
So, basically I had gone through the following scenario today. Went to work office, plugged in ethernet cable, ifplugd tried to connect to any of the networks specified in the profiles but failed to for whatever reason. No meaningful explanation. All it said was this:
Jan 27 09:44:57 localhost ifplugd(eth0)[27597]: ifplugd 0.28 initializing.

Jan 27 09:47:39 localhost ifplugd(eth0)[27597]: Exiting.
So, I had to do netcfg -u $PROFILE to set up network connection manually. Then I went back home, where I use wireless ap to connect to the home LAN, I saw ifplugd detect that ethernet had been down so it properly unconfigured eth0, again /var/log/everything clearly stated that
Jan 27 14:03:00 localhost ifplugd(eth0)[28240]: Link beat lost.
Jan 27 14:03:11 localhost ifplugd(eth0)[28240]: Executing '/etc/ifplugd/netcfg.action eth0 down'.
Jan 27 14:03:11 localhost ifplugd(eth0)[28240]: Program execution failed, return value is 1.
but nothing was happening for wireless interface at all. This was registered in the log when I got bored with netcfg/wpa_actiond not doing my job for me so I ran /etc/rc.d/net-auto-wireless restart which configured wireless network connection:
Jan 27 14:12:59 localhost wpa_actiond[4401]: Starting wpa_actiond session for interface 'wlan0'
Jan 27 14:13:00 localhost wpa_actiond[4401]: Interface 'wlan0' connected to network '$ESSID'
I think my configuration is correct but well I could've missed something of course. So, to save us time:
- all profiles are in /etc/network.d/. one of these looks like this:
% cat /etc/network.d/home-wifi
CONNECTION='wireless'
DESCRIPTION='A simple WPA encrypted wireless connection using a static IP'
INTERFACE='wlan0'
SECURITY='wpa'
ESSID='$ESSID'
KEY='$KEY'
IP='static'
IPCFG=('addr add dev wlan0 $CIDR/IP brd +' 'route add default via $IP')
DNS=('$IP')
POST_UP="sh /home/$USER/scripts/netcfg-home-post"
- /etc/rc.conf:
# net-auto-wireless support
WIRELESS_INTERFACE="wlan0"
WIRED_INTERFACE="eth0"
DAEMONS=(... !network @net-profiles net-auto-wireless net-auto-wired ...)
no ROUTES, no INTERFACES. Clean and neat. No syntax errors.
Software installed:
ifplugd 0.28-7
wpa_actiond 1.1-1
netcfg 2.5.4-1
So far the problem is that ifplugd can't connect to a wired network, but at least it attempts to, while wpa_actiond does nothing at all.
I really want my laptop to do this automatically. It's like... you know... 2011 already! Computers must do this stuff xD

Netcfg: net-auto-wireless missing

Maybe I just don't know the actual reason, but can someone tell me why netcfg installs net-auto-wired into /usr/bin but not net-auto-wireless? To get it to work I've been having to copy it into /usr/bin. Is there something else I should be doing?

[SOLVED] Netbooting with PXE, TFTP and NFS / Numerous errors

Greetings all, hope you can help me out.
Been given a task by my company of making a network bootable ICA client (with X and Firefox, with the Citrix ICA client installed) as small as possible to minimize network traffic (as 440 workstations would be downloading the end-product simultaneously, so it'd beat ten bells of proverbial out of the core and edge switches for a little while). I discovered two options. One being to integrate everything in side a cloop image directly inside the INITRD. I have stacks of working INITRDs with their matched kernels yet being my first dabble in to extracting the INITRD, my faffing with CPIO has resulted in me nuking my base layout (Thank god for snapshotting in VMware Workstation!) 4 times, and either getting "Premature end of file" or a copius amount of lines stating "cpio: Malformed Number: <strange characters>" finally ending with "Premature end of file". As a result I went in search of another option, which would be booting off an NFS share. I followed the guide:
http://wiki.archlinux.org/index.php/Dis … t_NFS_root
...in order to set up a network booted install of Arch and hit a few snags along the way, probably a result of using multiple operating systems for the TFTP and NFS server as opposed to using what the guide recommends, but I'm not sure as these seem solvable, although I don't know how right now.
The set up:
DHCP is provided by a Microsoft Windows Server 2003 VM (AD Integrated) on 172.16.10.17 on a box called "Rex".
TFTP is provided by another Windows Server 2003 VM by "TFTPd32" which is a free download. This is located on 172.16.10.158 on a box called "Terra".
The NFS store is provided by OpenFiler 2.3 which is a specialized version of rPath Linux designed specifically for turning boxes in to dedicated NAS stores. This is located on 172.16.10.6, and is called "frcnet-nas-1".
The problem:
DHCP is correctly configured with a Boot Host Name (Which is 172.16.10.158) and a boot file name of "pxelinux.0". This is confirmed as working.
Client gets the kernel and INITRD from TFTP and boots up fine until it hits "Waiting for devices to settle..." by which point it echos out "Root device /dev/nfs doesn't exist, attempting to create it...", which it seems to do so fine. It then passes control over to kinit and echos "INIT: version 2.86 booting" and the archlinux header, and immediately after that it prints:

...and, nothing after that, it just stops. Kernel doesn't panic, and hitting ctrl+alt+delete does what you'd expect, a clean shutdown minus a few errors about filesystems not being mounted. It seems /proc isn't getting mounted because init apparently doesn't have the appropriate permissions, and /proc not being mounted causes a whole string of other issues. Thing is, proc gets created at boot time as it contains kernel specific information about the system and the kernel's capabilities, right? Why can't it create it? How come init doesn't have the same privileges as root as it usually would, and how would I go about fixing it?
I admit, while I'm fairly competent in Linux, this one has me stumped. Anyone have any ideas?

The idea behind the Windows DHCP and TFTP is that we'd be using an existing server and a NetApp box with NFS license to serve everything off. I would have loved to make a new server which is completely Linux, but my boss, nor the other technician have ever used Linux so if I left for any reason, they'd be stuck if ever they ran in to trouble, which is why I've struggled to get Linux to penetrate our all Windows infrastructure.
During my hunting around on Google I found a lot of information on making my own initrd, and a lot of it using all manner of switches. I can make them fine, but I figure that I would need to look at extracting the current working one first, adding X, Firefox and the ICA client to it, then compressing it again. Cloop came about when I was looking at DSL's internals. The smaller the initrd, the better, so utilizing this could possibly be a plus too.
The reason I'm doing this with Archlinux is that I know Arch's internals quite well (and pacman is just wonderous, which is more than I can say for yum), so if I run in to a small problem I'm more likely to fix it without consulting Google. Fair enough though, the NFS booting method is giving me issues I never thought were possible. Ahh, sods law strikes again.
Addendum: I've noticed something which struck me as odd. Files in the NFS share are somehow owned by 96:scanner instead of root:root. Upon attempting changing, it's telling me "Operation Not Permitted". Further prodding has led me to believe it's an Openfiler thing where GID/UID 96 on the OpenFiler box is "ofgroup"/"ofguest". Chowning / to root:root puts NFS boot right ahead and gives me a prompt, however I cannot log in as root. I've also discovered that chrooting in to the base from my Arch workstation and creating a directory makes the directory owned by ofgroup:ofguest again, so it's an Openfiler thing after all this time. Prodding further.
Addendum two: For anyone using Openfiler out there, when you allow guest access to the NFS share, be sure to set the Anonymous GID and Anonymous UID to 0. By default it's 96 and as a result when trying to boot you get the errors I experienced. This is insecure and you should use some sort of network/host/ip range restriction. Because the root filesystem has 96:96 as the owner of everything after you install the base layout using pacman (and any changes you make afterward) init and root no longer have the appropriate permissions, user 96:96 (which is "scanner" in Archlinux) has the permissions instead and init, in order to complete boot would need to be "scanner" in order to boot completely.
Solution is to set Anon GID and Anon UID to 0, chown the entire diskless root filesystem to root, then use a linux desktop to mount the diskless root filesystem, mount /proc, /sys and mount bind /dev, then chroot in to the diskless root filesystem. At this point to clear up any problems with bad passwords, use passwd to change your password. Exit the chroot environment then unmount the diskless proc, sys and dev. Boot up via the network and use your chosen password to log in as root. At this point, start clearing up permissions from the en masse filesystem chown and you should then have a usable diskless root.
I'll experiment further and clear up some of the remaining permission errors that occured during boot and report on my progress in fixing it. Didn't like the idea of chowning the entire share as root. :S

[SOLVED] Cloning boot and var partitions to a new drive for booting

Ok first of all here's my setup:
fakeraid (dmraid) / and home on an OCZ Revodrive
boot with GRUB on a flash drive (since fakeraid doesn't support grub)
var and downloads/media folder on a 500GB WD Caviar drive
When I originally installed Arch I had the Caviar drive in my home server in a RAID5 array, so that's why I opted to install boot and grub on a flash drive simply for booting. Now that I have the drive in my desktop I've cloned the flash drive's partitions and MBR using dd:
#dd if=/dev/sde of=~/MBR.img bs=512 count=1
#dd if=/dev/sde1 of=~/boot.img
#dd if=/dev/sdc1 of=~/var.img
I then backed up my downloads/media partition, then removed the partition table, then used dd to put the img files on the Caviar drive.
#dd if=~/MBR.img of=/dev/sdc bs=512 count=1
#dd of=~/boot.img of=/dev/sdc1
#dd of=~/var.img of=/dev/sdc2
I also created labels for the filesystems and put those in fstab.
I'm able to mount both partitions, however I can't boot from the drive. I get a 'grub hard disk error' (no error number) when I put it as my first drive in the BIOS.
I can still use the flash drive as the first hard drive in the BIOS and boot from it, then it mounts the dmraid root partition and boots successfully. It is also able to mount the var and boot partitions in fstab.
Basically the only problem is that the MBR is somehow wrong. I then tried booting back into an Arch live USB and installing GRUB from the prompt:
grub
grub>setup (hd4,0) (in this case the Caviar drive's boot partition was /dev/sde1
So essentially what I'm asking is how GRUB handles the MBR. Is it specific to the partition table of the drive in which it resides when it's originally installed? For instance, since I had an 8GB flash drive with 2 partitions when I installed GRUB, is the backed up MBR no good for a 500GB drive with 3 partitions?
I have everything backed up so I can start with a fresh /boot and /var if need be....I'm just not sure where to start.
Thanks in advance.

Sorry, I forgot to mention that I tried to install GRUB from the GRUB shell in a live Arch USB. It failed on a few non-critical parts, and succeeded on the last part. I'm going to try again shortly, possibly I did something wrong. GRUB is able to find the stage files using:
#grub
grub>find /grub/stage1
grub> find /grub/stage1
(hd0,0)
(hd5,0)
grub>
(hd0,0) is the desired boot drive, while (hd5,0) is the current bootable flash drive with /boot and GRUB installed.

I'm using dmraid, so just to be clear I've configured the raid using:
#modprobe dm_mod
#dmraid -ay
Then I saw the array stored in /dev/mapper/silXXXXX. I then created partitions for /boot, /, and home. At that time I was hoping to get GRUB working with the AUR package grub2-dmraid. I wasn't able to get it working for some time, so I just went ahead and installed boot and GRUB to a separate USB flash drive.

Also I don't have a /proc/mdstat. That's only for mdadm RAID setups, right? It's been quite some time since I've used mdadm so I can't remember.
EDIT:
So I booted into a live Arch USB and entered the grub shell. I ran:
#grub
grub> root (hd3,0)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd3)
Checking if "/boot/grub/stage1" exists.....no
Checking if "/grub/stage1 exists.......yes
Checking if "/grub/stage2 exists.......yes
Checking if "/grub/e2fs_stage1_5 exists....yes
Running "embed /grub/e2fs_stage1_5 (hd3)".....25 sectors are embedded.
succeeded
Running "install /grub/stage1 (hd3) (hd3))1+25 p (hd3,0)/grub/stage2 /grub/menu.lst".......succeeded
Done.
Last time I recall more errors than this, then it reporting that one was a non-critical error, so I think the problem may be solved. More to come.

OS X extern drive ownership/permissions and NFS exporting

- I have an external (250GB) firewire drive on OS X 10.4.9.
- I want to have it available to local users of this Mac but with ownership/permissions of created files/directories protected in the usual UNIX sense of unique UID/GID -- files/directories created by one user cannot be read/written by other users of this Mac except as allowed by standard UNIX permissions groups settings; eg., those set with 'chmod' command.
- I want to NFS-server this drive volume to a linux NFS client (eg., RHEL 4), again with files/directories protected in this same UID/GID UNIX sense. In our case, the users' UID/GIDs will be made to match, but regardless, I wish likewise for file/directory use on the linux client to be restricted as per UNIX permissions and the files/directories created by the Mac users have protections remain in place against linux user access, and visa versa, as above.
Is this feasable in Mac OS X (without OS X Server)?
How does one go about acheiving it?
I have basic Netinfo Manager skills for creating NFS exports and starting NFS daemon services, but am not expert on all available export options. I have average linux IT NFS server/client and user management skills.
Thanks,

I don't know about networking with Linux, but I don know that for OS X users, enforcing permissions on an external drive without OS X Server is tricky.
First, log in to your admin account. Right-click the drive, Get Info, expand Ownership & Permissions, and uncheck "Ignore ownership on this volume". Then set permissions accordingly.
The problem is that any unprivileged user can log in to his own account, Get Info, recheck the box, and get ownership of the entire contents of the drive. This is possible even without the admin password.
There is a workaround that will remove the Ignore Ownership box from the Get Info panel so that there will be no box for them to check. First make sure that the box is unchecked and that the permissions are set how you want. Then enable ACLs on the volume by entering this command in a Terminal window:
sudo fsaclctl -p /Volumes/volumename -e
Then restart Finder. Now there's no box for the unprivileged user to check. But I don't know where this setting is stored; perhaps the unprivileged user can find some command-line way of getting the box re-checked and thus getting ownership of everything.
If there is some way you can get the data off of the external drive and onto the main boot drive you will have the best chance of keeping the data safe.

It should be like the very first time you synced your phone with I-Tunes. It will notice you haven't synced before and just copy everything from your phone into I-Tunes. It shouldn't delete anything from the phone, at least it never has for me. It just puts a copy of everything into I-Tunes and even if you delete an app for example from your phone and you decide you want it back later, you can just go back into I-Tunes and copy it back over. Hope this helps.

Snow leopard server for net boot and software updates only what needs to be running to use it?

Snow leopard server for net boot and software updates only what needs to be running to have it work right?

Netboot and Software Update, at its simplest. Mac OS X Server also expects to have functional IP networking and DNS services (somewhere) on the LAN (and if you're behind a NAT gateway, then the DNS server(s) are on your LAN and not out at your ISP), or things get weird. SUS (usually) works out of the box, outside of cases where there's an outbound firewall. Netboot can be more effort to setup, in terms of what you're loading into the clients.

Trying to do pxe-boot and kickstart install on sunfire x4150 using NET MGT

I am trying to do pxe-boot and kickstart install on sunfire x4150 using NET MGT port. Is this doable? The eth0 port works fine, but the NET MGT port does not seems working. It gets the IP, gateway, mask and other info, but would not start the install. I heard that the NET MGT port is not capable of doing pxe-boot, please let me know if this is true.
Your help is appreciated.

The NET MGT port is for the ILOM. That interface is not visible to the Host OS so no it cannot be used for host communication including PXE booting...

[SOLVED]Incorrect mountpoint for /home and /boot

Hello Archers,
I'm new to Arch, if you find my question is so dummy, let me know
I have manually setup the partition like this:
1. sdb1 NTFS with boot flag toggle, primary (My existing Windows XP)
2. sdb2 with boot flag toggle, primary (will be used as /boot), type 83
3. sdb5 logical (will be used as swap), type 82
4. sdb6 logical (will be used as /), type 83
5. sdb7 logical (will be used as /home), type 83
6. sdb8 logical NTFS
I have a small problem when installing Arch, it's about setting up filesystem and mountpoint.
The installer asked me to select the swap, I chose sdb5, for / I chose sdb6, and it asked me to select additional partition to be mounted under new root, I chose sdb5 with the mount point /boot, sdb7 for /home. The installer show a summary of the filesystem and mountpoint before it makes changes to the hdd, everything is correct. But when it makes changes to my hdd, it said that it make a mountpoint at /mnt/boot and /mnt/home.:rolleyes:. It should make mountpoints at /boot and /home respectively. Why does it add a prefix /mnt to my custom mountpoint?
It seems to be a bug in the installer.
Any help are appreciated.
Thanks
Tinh

If so, the message generated by the installer is confusing, it need to be fixed to save some posts like this on the forum:D
I'm not at that computer right now, so I cannot verify this. I will verify this problem in the evening and report back.
Thanks for a quick reply.
