Complete arch (system) documentation?

Hi. I would like to have arch and it's mechanisms and infrastructure completely documented. Of course this could be quite a large task, but i think people like me (who like to read the manual before using stuff) would appreciate this, and it would also serve to leverage the overall knowledge of archlinux, so that less people would ask "stupid questions" (i don't mean it like that.. ) on the forums.
I also understand that this could realistically only be done for a "base" install arch system, as X11 and other applications/services go beyond the scope of such basic documentation.
The reason i would like this is because i couldn't find anything like this on the wiki, _and_, it would also be nice to have something compiled in a form you could print out. (ie without further references, but a compilation).

As far as a doc for experience users though i think that would be a waste, since most experienced users wouldn't need a doc to let them know how to edit a linux system.
Not the arch linux specifics, take the init system as an example. How, and what files are used. How to write your own init/daemon. Did you for example know that daemons get registered in /var/run daemons when succesfully started? And that rc.multi/functions is responsible for that (and how)? Or that rc.sysinit is resposible for setting you system locale?
Or how to use makepkg/makeworld in archlinux? Again, even if there already is a wiki entry about this, it should be a part of a compiled doc covering basic system maintenance in arch.
Some of the already present wiki articles (like setting up a network connection) though already existing, should be a part of this documentation. If necessary, expand them.

Arch Linux Documentation

Is anyone in charge of developing Arch Linux documentation? From an interview that I came across on the net, I gather that there is. If so, could I ask what the programme is to improve documentation and what the target dates are?
If there isn't anyone in charge, are there people who would be interested in working on documentation, maybe within the Arch community, but maybe outside on an independent site?

I get the sense that there are a lot of people involved in this distribution who like to pretend that deficiencies are strengths. I also think that the distribution is undermanned. Normally, if a project is undermanned, the idea is to bring people on-board. Trashing people who explore the possibility of getting on-board, and who in the process ask some hard questions, given that getting on-board involves a commitment of time and effort, is not necessarily a clever strategy.
Anyway, having read through this thread, the question in my case is now academic. There is no way that I am going to dedicate 8-10 hours a week to documentation is if people think that spare documentation is a badge of honour. Besides, it is so much easier to write the occasional post.
This is all fair enough; if you don't feel that your efforts would be useful, then by all means don't "waste" time on it (I say this from the point of view that I think you should feel fulfilled by your contributions to this kind of community, not "I didn't like what you said, so I don't want your help" kind of way ) . I think a lot of the feelings expressed in this thread are summed up by the last line of your post, but in a more positive way. That is to say, the Arch Forums are fantastic, and people are willing to answer questions that come up here. As a result, they are maybe unwilling to spend time adding stuff to the wiki that may be too general to cover specific questions anyway. I do think there are a lot of projects and common questions that can be summed up in informative wiki pages (and a lot of things *are* covered there). Perhaps naturally, the wikipages that *do* get written are ones that involve projects people are personally involved or interested in (I put in a wmii wiki page at one point when I got into ruby-wmii, but even that has fallen behind wmii releases at this point).
There have obviously been documentation efforts, and plenty of people that stop by to say "Hey, I'd like to help". However, I think the stopping point for a lot of people is either a) What needs documenting and b) Gee, I don't know anything about the stuff that needs documenting! I actually think the best wikipages are born of arch forum threads; when a discussion has a lot of great tidbits, somebody usually chimes in and says "Hey, somebody make a wikipage", or better yet, "Hey, I already made a wikipage, check it out and add stuff if you want". This works, because obviously a lot of people reading the threads that end up creating the wikipages *know* about the subject. Also, people are immediately alerted in the thread that there's a new page, and may say "Hey, I can add to that", as opposed to a system where people are just going through adding pages and hoping other people notice and add stuff too.
So, in summary, I guess I'd say that documentation is great, but due to the nature of Arch, our efforts work the best when the ball is already rolling in the forums. Which really is the best way for a "smaller" distro like Arch, IMO. Maybe to you this still seems like a "deficiency" that Arch users think is a strength; it seems to me to be more of a natural product of a really active user community (where instead of there being a group of people dictating what documentation is needed and such, those things that come up in community end up being codified in the wiki).
Personally, for me, I think a good documentation effort would be to keep your eye on long or very active threads; if they look like they have juicy info in them, condense it into a wikipage and announce it in the thread. Of course, that's just one Archer's opinion, and not necessarily of one that knows what he's talking about . I do agree that there are steps that could be taken to make tackling documentation easier (and I am aware that Dusty has the "Wiki volunteers wanted" thread for this) for people that "want to lend a hand", and I'm certainly not saying the efforts that have gone on so far have been wasted. I just like the idea of the really active community in the forums being leveraged to help the "static" documentation in the wiki. See a thread that indicates the install guide is lacking info is confusing? Make the wiki edit! See a thread with great new info? Start a new wiki page! See a thread born of BAD INFORMATION in the wiki? DEFINITELY update the wikipage! Embrace the wikiness of the documentation; worry less about "who maintains this page", and more about "what are the actual issues users are having, and can I change something right now to help?". Coming from this angle really reduces the feeling of being overwhelmed when loading up the wiki to edit it with no particular agenda in mind... rather, you have particular pages in mind, and you know they will be immediately useful.
Cripes, this was a long post. Sorry! Hopefully it will encourage people to contribute, even if it's just a small edit on a single page, without them worrying about becoming documentation maintainers. You don't have to be an expert at everything or anything, but being a part of a community is contributing what you can when you can. Oh, and yeah, this post probably looks funny coming out of the mouth of an "Occasional poster"; I'm actually on the forums daily, looking for spots where I can answer a question, and do so when I can.. my lack of posts is simply an indication of my not knowing enough .
Oh, and as to the response to Dusty's response... I feel like we see these kind of responses a lot on the forums, and I kind of wish people wouldn't take such umbrage at these comments. These comments are a result of people *knowing* the community. It doesn't mean that they think your idea is stupid, it just means that they're telling you what has been true in the past, and why certain things maybe don't work out. It doesn't mean you shouldn't feel like you can contribute how you want; it's open, go for it. Get the ball rolling; the community may embrace it gladly. If it didn't, well, you contributed out of love of the community, and that will certainly still be appreciated.

Time Machine will not complete a system backup and terminates with "Unable to complete backup. An error occurred while copying files to the backup volume. This follows a problem when Time machne terminated when the volume was almost full.

On 11/1/2011, Time Machine (TM) terminated with an error message I did not record. I noted that the drive was full and decided to do a separate complete bootable system backup using Carbon Copy Clone (CCC), before clearing the TM volume and trying to start it over clean. Part way through the full system backup CCC put up a message that there was a Physical Problem "Library/Application Support/Techtool Protection/McIntosh HD/Directory Backup 2011-11-01-16-28-16". That was about the time that TM malfunctioned, so I assumed they were related. After starting CCC over a couple of times, and getting the same error message, I let it go through to completion of the backup, which took three or four hours. I then ran tests using Disk Utility and verified that there was nothing physically wrong with both the internal hard drive and the TM volume. I also erased and reformatted the TM volume. However, every time I started Time Machine, it would record a few GB and terminate with "Unable to complete backup. An error occurred while copying files to the backup volume". I restarted the computer with no change in results. Note that prior to starting the CCC backup, I "Repaired Permissions", "zapped the PRAM" and "re-set the SMC", hoping to have a clean bootable system on the backup. I ran Techtool and no problems were found.
I'm running this on an Intel iMac under 10.5.8 and recording to a 500GB My Passport drive. My hard drive is only about half full at 246 GB. My assessment is that something happened at 16-28-16 on 11/1/2001 to screwup the Backup Directory in the file at "Library/Application Support/Techtool Protection/McIntosh HD/Directory Backup 2011-11-01-16-28-16". My question is, how do I fix it?
I had just completed writing everything above here, explaining the problems I had been encountering for the past 24 hours. I had the Time Machine window standing open on the desktop where I could see it, having recentlycleared it after the last termination. As I was proofing what I had written, I looked at the window and noted that the clock had started a new run for a full back up, since all prior efforts had failed and the TM volume was empty. As I watched and waited for it to fail again, as it had been doing at about 13 GB, it kept going and going until it just finished a complete backup, about 4.5 hours later, with my having done nothing. Now my question would have to be - what could possiibly have happened to make it perform this way? It will be interesting to see if it continue to operate normally, or if the problem will return, in a later backup run.

You should not keep those files for long, and probably shouldn't back them up (if you need them at all -- since you do regular backups, I'm doubtful just how worthwhile that feature is).
"Unable to complete backup. An error occurred while copying files to the backup volume".
One of Apple's maddeningly incomplete messages. Most likely, there's a problem with a file (quite possibly the one CCC didn't like). See #C3 in Time Machine - Troubleshooting for details and instructions on finding and fixing it.
If you continue running the Directory Protection app, be sure to exclude your Time Machine drive from it (as it will just take up lots of room, and won't help repair your backups if there's a problem); and exclude the folders it creates from being backed-up by Time Machine (as they'll create large backups, and you probably can't use the backed-up folders anyway), per #10 in Time Machine - Frequently Asked Questions.

I completed a system restore with no backup. can i recover my files?

Hii
I completed a system recovery to factory condition and i had backed up my files too. it turns they hadnt been backed up so now i have lost all my files. Is there any way i can retrieve my files, any way at all please???

Where did you save the backup files? If they are on dvd or external usb hdd look for an .EXE file in the list. Run it to extract the files to a folder on your laptop.
If you saved backup files to the D;\Recovery partition before resetting they may be gone. Try Easeus Data Recovery on the C drive to see if any can be found:

ArchTaz Live: boot and run an Arch system entirely in RAM

ArchTaz Live Boot: A method to boot and run an Arch system entirely in RAM using tmpfs.
As the name suggests it was inspired by (copied entirely from) SliTaz http://www.slitaz.org/ and boots in exacly the same way.
It needs a custom init script in the root directory and for some reason that I can't work out a hook for sysinit_premount in rc.sysinit to remount / rw.
The /usr/bin/archfs script is just a chunk of Slitaz's Tazusb utility with some minor changes (and I haven't properly tested the lzma or no compression).
The /init script is modified from the usual initramfs /usr/lib/initcpio/init with hints from the SliTaz /init script (and some personal additions for my system).
Copy init to the root directory, run archfs (eg. # archfs writefs gzip) and move the resulting archfs.gz to your boot partition/directory and boot with archfs.gz as your initrd.
I run a fairly light system (Openbox, Firefox, Gnome-Mplayer, SpaceFM, no dev packages) and gzip compression gives me an archfs.gz just over 230MB that boots in just over 30 seconds using 138MB RAM on startup, and most applications start instantly (2GHz Core2Duo, 4G RAM). Lzma compression generally gives a smaller archfs.gz but takes longer to boot. I have a persistent home partition, I install packages as I need them and then they're gone on next reboot if I don't do a new archfs.gz to keep them. I delete man pages, unneeded locales, etc. Obviously if you're running a hefty install on a limited box you may run into problems.
Any tips, cleanups, corrections welcome. It's been a mostly copy and paste and mash stuff together process so it isn't neat. And I think I may need some serious help when systemd becomes default.

Oh yes any man directory was symlinked to /tmp long ago, so they don't even get installed.
Right, new boot process:
Using hooks in normal initramfs-linux.img to unpack archfs.gz into tmpfs and boot it.
Create an initcpio preset file /etc/mkinitcpio.d/archfs.preset:
# mkinitcpio preset file for the 'archfs' package
ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux"
PRESETS=('archfs')
archfs_config="/etc/mkinitcpio.conf"
archfs_image="/boot/archfs-linux.lzo"
archfs_options="-S fsck -A tmpfs -z lzop"
Or append to the standard 'linux.preset' file so the initramfs is created automatically when you upgrade your kernel. Or alter /etc/mkinitcpio.conf to add options.
Create the file /lib/initcpio/hooks/tmpfs:
#!/usr/bin/ash
run_latehook() {
# Mount tmpfs root
mount -t tmpfs tmpfs /mnt
# Unpack rootfs
msg "Unpacking rootfs..."
cd /mnt
# parse the kernel command line

This loads modules and fsck binaries for the filesystem of my /boot partition into the initramfs. It also adds all the relevant compression binaries (some which can also be compiled into busybox or left out if not needed). I'm working on automatically reading the filesystem from your /boot partition based on the "root=" kernel command line option and adding the appropriate modules.
Create a new archfs.gz (or new extensions) with new cleaned up /usr/bin/archfs:
http://pastebin.com/xiqgyYyL
Now run with:
# archfs lzo
(or whichever crompression you choose). It also takes care of any mounting directories you have in /mnt. And "writefs" is no longer needed, that's all it does anyway.
Then simply add the "root=(your boot partition)" and "archfs=lzo" (or whichever compression you chose) command line options to your grub.cfg.
Run:
# mkinitcpio -p archfs
That'll create an initramfs: archfs-linux.lzo that you need to move to your boot partition with your kernel and archfs.gz. Then point grub to that as your initrd.
This will boot and the tmpfs hook will do it's work just after init has mounted your boot partition and then init will switch roots and run /sbin/init as it would on any normal install.
Mix and match as needed. You can remove the /init file from the root of your filesystem or leave it there and all but an xz compressed archfs.gz will boot the old way aswell (the kernel can't handle the xz version). It should all be fairly upgrade proof, barring any major changes to mkinitcpio.
Boot for me with lzo compression is at least twice as fast as old method. Partly due to lzo compression which is super fast (especially creating the archfs.lzo). It makes for a bigger file but it's still only 350MB (pretty much half my uncompressed root filesystem).

Make LiveCD of current Arch system

I would like to make my current Arch system bootable from CD/DVD/USB.. So I can boot it on any PC just like it is, that will not make any changes to PC that will boot it, etc.
Thanks

That's kind of vague, and unless you have a very minimalistic arch install, I doubt it's feasible to do with a CD. I'd say a USB thumbdrive would probably be your best option so that you wouldn't be slowed down by your optical drive reading everything off a DVD. I think it would probably just be easier to install Arch on to a USB drive and copy over all the necessary config files for the programs you'd want to use on it. I'm pretty sure most of what you'd need to do this is already available on the wiki. Check out Here and the beginners guide if you need it, and you should be able to do all this on your own.
Edit: Well, I was beaten to it while looking around for stuff. Still, everything you need is out there already, here or on the wiki.

[SOLVED]possible to make live image of a current running arch system?

Hi Friends!!!. Is it possible to make live iso image of a current running arch system? are there any tools available for that?(I want to do this cause When i install a new arch system, I want to remain my own customizations intact)
Last edited by Pranavg1890 (2012-10-14 07:29:58)

OK, so after reading the posts, I think that this is not possible.but i think this sould be feature which should be researched upon cause everytime I install arch on a new machine(arch reinstalls on same machine are very rare cause it's a rolling release and has excellent recovery tools) I have to spend a 5-6 hours of time configuring the system.so, i think it should be a feauture that should be worked upon.for eg. like you could chroot into the iso created and then replace the deafult configs by the one on your system or a system scanner which scans the changes on the system with respect to default arch installation and make the necessary changes to the live image.Thanks friends for your replies. I mark this thread as solved.

Using iTunes again after complete op system reload

My windows XP machine got trashed by a virus and has had a complete op system reload. When I re-installed iTunes it found my old library on the disk but now iTunes refuses to sync with my iPod as it says that the iPod is linked to a different library.
Is there any way to persuade iTunes that it is in fact my library so that I can carry on using it as before ?
My iPod is a iPod Touch - 2nd generation - and has been upgraded to the latest version of the op system (3.x from memory).
Many thanks

well done, NoahsMyBro!
hmmmm. some thoughts (speculation warning) on what might have gone wrong with the QT. a system restore "over top" of a fresh itunes install will strip out some installation registry entries from both QT and itunes. (under those circumstances, itunes won't launch, spitting out a "some of the required files ..." error message.)
under those circumstances, i usually recommend uninstall QT and itunes prior to the reinstall. (of course, you had other more pressing things to worry about at the time ...) i've been doing that because the QT component of the itunes installer bundle can be a little more delicate than the itunes component when it comes to installing "over top" of existing program files and folders. i think it's partly to do with the fact that it's the second install in the chained install (more can go wrong with it). so the QT may have been compromised on the reinstall, even though the itunes part of the install went through fine.
you don't tend to get the same QT install problems on a standalone QT install (again, speculation, but it seems plausible) because it's not the second install in a chain.

Shutdown and Archiving of complete SAP system (GDPdU)

Hi all,
I am interested in possibilities to archive a complete SAP-system after it has been shut down. Archiving might be necessary due to certain legal requirements, e.g. the GDPdU in Germany. Which other requirements do you know, which ways of archiving do you prefer?
Thanks for your comments and advise,
Peter

Hi Peter,
I am currently involved in a project where we are archiving data off of multiple retiring systems. We are archiving our legally required data in the form of printlists since printlist are self-contained, unlike archiving objects. For US data, we are also archiving DART extracts as needed. The printlists and DART extracts will be viewable long term in a single remaining SAP environment (we are shutting down many environments and setting up one for archive access). The archive link information is being migrated from the retiring instances to the single remaining instance so that the data can be accessed from there.
Regards,
Kelley

Arch System Config Util.

Hi guys,
I started today to make a Arch System Configuration Utility, Now its very basic
and i got alot ideas on how to expand the program with more functions. It is
a basic text editor which lets you config the most important Arch config files on the fly.
The program was born because i as a light desktop user got fed up opening the same
old same old files over and over again in my FM, so whit this thingy i can open them on the fly.
There are probebly half a dozen more config files i could place in the app but this is just
the bare beginning.Hers the screeny:
It is very small and uses GTK.

here is the DL link.
I am planning for this program to make it able to start,stop,restart services and display a bunch of system stats really not sure yet
if you have suggestions post To be able to save the files you must run it as root eg, sudo
Enjoy..

Hey guys,
To reply some words to the people placing comments on this little app.
If i hadn't seen the topic of this treat i would never have posted it, i am sorry
if that offended some people because that was and would be never be my intention
also i am not a real dev , this is stuff written in gambas2 LOL. its for fun.
I just wanted to share something i worked on for personal use that maybe
people could think of as semi usefull.
This little project was just a thing to keep me bussy and get used to the Gambas2
IDE, that being said:
I am still working on this thing and wont post any of it anymore before i think it would
be even worthy of making a PKGBUILD for (which might never happen), and then this:
the source that gambas2 gives can (to my best knowledge) only be compiled with the
gambas2 IDE), Just saw it CAN make a source archive just not sure to what extent this can be
compiled with gcc Thats wy i was posting the stand alone binary files.
Anyway in the version that has not been posted:
* Combo drop down box to have a look at the most used log files on arch linux. (finished)
* Search box + filter to search for keywords in the currently displayed log files and a
a filter SO displaying only the lines in log files i am looking for (being worked on atm)
* Controls and drop down box with to the most common system services one would mostly want
to start, stop or restart) (being worked on atm, controls already done)
* A small CLI window under the text output box , to catch the output of the systems services
start / stop / restart (being worked on, CLI running but working on the piping of the commands to it)
* Resizing of the hole application without buggering up the positions of the buttons on top and
botton (finished)
this is what it looks like atm.

[SOLVED] Remote Access to a home Arch system behind the router.

Hello,
I am trying to remotely access my home Arch system from school. I did try doing something and this is what I did:
1. Used DynDns and NO-IP to setup a free domain, I thought NO-IP script was easy to run so I tested this on NO-IP.
2. I then installed Openssh.
3. Then I have setup the Port forwarding on the router to point to my ssh port (change from 22).
4. I tried to ping, the domain name from NO-IP with no response.
What I want to ask is... is there any better way of doing this?
I dont need a desktop access, simple ssh should do for now.
Thank You
Gopi

OK, I have solved this by this process. Will work only if the router supports the DynDNS. I am assuming that you have created a DynDNS account, its free for 2 domains. I also had to make my computer use STATIC IP from my router, just specify any IP address outside the DHCP range.
1. On the router, add the details about the DynDNS account. On my Belkin Router, I had to go to Firewall -> DDNS -> DynDNS and give the details and also enable it.
2. By doing the above step, we don't have to install the client for DynDNS.
3. On the router again, setup the port forwarding, again (on my Belkin Router) go to Firewall -> Virtual Servers -> Add the IP and the port numbers, I had to use the same number for both the incoming and the private port, though for other routers the number can differ?
4. On the computer, I installed the openssh and then changed the login port to the one specified in the router for forwarding.
5. Make the router and ssh logins as safe as possible. I understand that opening the router is not safe so I have to warn you.
I can now login using my DynDNS domain name from anywhere woohoo!
