Thanks tlaloc! I transferred that list of articles over to the Arch Press Review wikipage under the German Language section, and included a link back to the German original. I also fixed a tiny spelling error in the German page. I also doublechecked all the links to make sure they are live. As the French would day, "J'encule les moustiques"

Backpac: A package state snapshot and restore tool for Arch Linux

backpac:
A package state snapshot and restore tool for Arch Linux with config file save/restore support.
https://aur.archlinux.org/packages.php?ID=52957
https://github.com/altercation/backpac (see readme on the github repository for more information)
Summary & Features
It's a common method of setting up a single system: take some notes about what packages you've installed, what files you've modified.
Backpac creates those notes for you and helps back up important configuration files. Specifically, backpac does the following:
maintains a list of installed groups (based on 80% of group packages being installed)
maintains a list of packages (including official and aur packages, listed separately)
maintains a list of files (manually created)
backs up key config files as detailed in the files list you create
The package, group and files lists along with the snapshot config files allows system state to be easily committed to version control such as git.
Backpac can also use these lists to install packages and files. Essentially, then, backpac takes a snapshot of your system and can recreate that state from the files and lists it archives.
Use Cases
Ongoing system state backup to github
Quick install of new system from existing backpac config
Conform current system to given state in backpac config
Backpac is a very, very lightweight way of saving and restoring system state.
It's not intended for rolling out and maintaining multiple similar systems, it's designed to assist individual users in the maintainance of their own Arch Linux box.
Status
Alpha, release for testing among those interested. Passing all tests right now but will continue to rework and refine. Bug reports needed.
Why?
There are a lot of 'big-iron' solutions to maintaining, backing up and restoring system state. Setting these up for a single system or a handful of personal systems has always seemed like overkill.
There are also some existing pacman list making utilities around, but most of them seem to list either all packages or don't separate the official and aur packages the way I wanted. Some detect group install state, some don't. I wanted all these features in backpac.
Finally, whatever tool I use, I'd like it to be simple (c.f. the Arch Way). Lists that are produced should be human readable, human maintainable and not different from what I'm using in non-automated form. Backpac fulfills these requirements.
Regarding files, I wanted to be able to backup arbitrary system files to a git repository. Tools like etckeeper are interesting but non /etc files in that case aren't backed up (without some link trickery) and there isn't any automatic integration with pacman, so there is no current advantage to using a tool like that. I also like making an explicit list of files to snapshot.
Sample Output
This is the command line report. Additionally, backpac saves this information to the backpac groups, packages and files lists and the files snapshot directory.
$ backpac -Qf
backpac
(-b) Backups ON; Files will be saved in place with backup suffix.
-f Force mode ON; No prompts presented (CAUTION).

If AUR_HELPER is defined by the user, then either you might need a list of major AUR helpers and their command line switches so you can pick the correct switch for what needs to be done (most use some variation of -S for installing, but not all), or have the user define the correct switch(es) somehow for their chosen AUR helper.
That's a good idea. I'll add that to my AUR refactoring todo.
I also found directory tracking to be a weakness in other dotfile managers that I tried. I think you would definitely have to recursively list out the contents of a tracked directory and deal with each file individually. Wildcard support would be nice...I just haven't personally found a use case for it yet.
I've been thinking that I could just add the directory and scan through it for any non-default attribute files. If those are found then they get automatically added to the files list. That's pretty close to what etckeeper does.
Edit: I just compiled the dev version and removed my comments for already fixed things...sorry!
The master branch should have those fixes as well, but I didn't update the version number in the package build. I'll have to do that.
1. Still apparently didn't handle the escaped space for this item: (the file does exist on my system)
Ok, good to know. This wildcard directory business will require some new code and refactoring so I'll also rework my filenames handling.
2. Suggestion: you should make that awesome README into a man page!
I was working on one (the pkgbuild has a commented out line for the man page) but I had to leave it for later. Definitely want a man page. Once this stabilizes and I'm sure there aren't any big structural changes, I'll convert it to man format.
3. Suggestion: add the word 'dotfile' into your description somewhere on this page, the github page, and in the package description so people looking for dotfile managers will find it. You could also consider modularizing the script into a dotfile manager and the package manager, so people on other distros could take advantage of your dotfile management scheme.
I actually have a different script for dotfile management that doesn't touch packages, but there is definitely overlap with this one. That script isn't released yet, though, and if people find this useful for dotfile management that's great. I'll add that in.
4. Suggestion: since -Q is a read-only operation, why not just make it run with -f automatically to avoid the prompt?
Originally, running backpac without any command line options produced the Query output. I was concerned that since it is a utility that can potentially overwrite system files, it is important to give users a clear statement prior to execution about what will be done. Since the Query output is essentially the same as the Update and System reports in format and content, I wanted to be explicit about the Query being a passive no-change operation. The current command line options aren't set in stone though. If you feel strongly about it being different, let me know.
Long answer to a short question
5. Another suggestion: any thought to providing some sort of 'scrub' function to remove private information from the stored files if desired? This would be cool for publishing public dotfiles to github. Perhaps a credentials file (I did this with python for my own configs). Probably detecting email addresses and passwords without a scrub file would be rather difficult because dotfiles come in so many flavors.
Yes, absolutely. In fact, if you look at the lib/local file (pretty sure it's in both master and dev branches in this state) you'll see some references to a sanitize function. The idea there is that the user will list out bash associative arrays like this:
SANITIZE_WPA_=(
[FILE]='/etc/wpa_supplicant.conf'
[CMD]='sed s/expungepattern/sanitizedoutput/g'
Question: am I missing an obvious option to remove a file from the files.d directory if I delete it from the files list? Or do I have to delete it manually? It might be helpful to add a section to the README on how to update and delete dotfiles from being tracked, and also a more detailed description of what the -b option does (and what is actually created when it's not used).
You are only missing the function I didn't finish. There should be either dummy code or a TODO in the backpac main script referencing garbage collection, which isn't difficult but I just haven't finished it. The idea being another loop of "hey I found these old files in your files.d, mind if I delete them?" It's on my list and I'll try to get it in asap.
And finally, just out of curiosity, why did you choose to actually copy the files instead of symlink like so many other dotfile managers do?
git not following symlinks, hardlinks also out for permissions issues (git wouldn't be able to read the files, change them, etc.)
I definitely would prefer to not make an entire copy of the file, but I haven't come up with a better option. Shout with ideas, though. Also, if there is a way around the link issues I noted above, let me know. I don't see one but that doesn't mean it's not there.
edit: I think a Seattle area Arch meetup would be cool! Perhaps coffee someplace? Bellevue? U-district? Anyone else? BYOPOL (bring your own pimped out laptop)
A general meetup sounds good. I was also thinking it would be fun to do a mini archcon with some demos.

Localepurge for arch linux

I just seeked for some thing to clean unused locales from my system and while I used gentoo I used localepurge, so I realize update this script for Arch linux
# unpac this package to your /usr/local (it will make sbin/localepurge and share/localepurge/*)
robertek.no-ip.org/files/localepurge/localepurge.tar.bz2
#copy this file to /etc/locale.nopurge (or wherever else but than you must edit /usr/local/sbin/localepurge)
robertek.no-ip.org/files/localepurge/locale.nopurge
!!!! Before run edit locale.nopurge file and write there your locales you dont want to delete !!!!!
Than if you are pretty sure that you edit correct locales just add "#" before NEEDSCONFIGFIRST
than you can run localepurge (/usr/local/sbin/localepurge if you dont have /usr/local/sbin in your PATH)
!!! BE CAREFULL THERE IS NO WARANTY FOR THIS SCRIPT AND DONT BLAME ME FOR CORRUPTING YOUR SYSTEM !!!! (anyone can just scroll the script and look if it is correct by you look)
For me it work great an I just delete more than 100MB of mess.
Feel free to make a package out of it I will be pleased (and please share).

Hi,please suggest me some games for Compaq CQ62-105TU Laptop.Can I upgrade my laptop's graphics card

Unfortunately, you cannot upgrade the processor or graphics card on this laptop.
Here is a page from CPU-World that gives the specs for your processor:
http://www.cpu-world.com/CPUs/Bobcat/AMD-E%20Series%20E2-1800.html
You will see down near the bottom of the page that it is not upgradeable. Some laptops come with the processor soldered to the motherboard. Almost all laptop graphics are this way. The only way that you would be able to get a faster processor/better graphics for this laptop would be to purchase a brand new motherboard. You can do an Ebay search for 'HP G6 motherboard' to see what average prices are if you want to go this route.

Crover - generate OS version numbers for Arch Linux

Arch is a rolling distro, but did you ever wish it still had release numbers? So you could check what "version" you currently have installed, and upgrade to the latest "version" if necessary, with a reasonable delay between versions?
Of course you didn't. No sensible person would want to attach pseudo-version numbers to a rolling distro.
https://code.google.com/p/crover/
https://aur.archlinux.org/packages/crover/
crover returns a version number for Arch Linux based on time elapsed since the distro's initial release (March 11, 2002). The number format is X.Y, with X being years and Y being subdivisions of the current year. By default, the version number is generated for the current date with a subdivision size of one week.
As of this writing, the current version is Arch Linux 12.1. In other words, Arch is 12 years and 1 week old.

Hmm, you could actually make this somewhat more relevant to actual update practices if you wanted. Were I to try to accomplish such a task, I would figure out a way to check and see if all the official repos are up-to-date (or just if all the packages the user has installed are up-to-date with `checkupdates`). Then, take the number of seconds elapsed since Arch's release till the last update (which brought that rig up-to-date).
Then, you could grab the user's list of currently installed packages with pacman and take a hash of it. And, by concatenating those two figures together, you could get some semblance of a "version" number. For example, mine would be something similar to the following:
378691200.4c41d609
Not to mention, with this calculation, it would not be difficult to format the time part of the version in a variety of ways. May be worth thinking about
All the best,
-HG

Ubuntu look-alike gnome theme for arch linux

Is there any theme/gnome package(s) for arch linux that will give me gnome that looks kind of like the gnome package for ubuntu? I'm moving over from ubuntu to arch, and I'm hoping to ease the transition at first while I get used to the rest of the system. Thanks!
EDIT: Actually, how configurable is xfce? I've used gnome and kde for arch a bit, but they're just so vanilla, and I'm still looking for a relatively nice graphical interface on top of cli. Thanks!

xfce4 is just about as configurable as GNOME at the level of gconf/ xfconf and way more configurable via the settings GUI.

.dotjs and .dotcss for Arch Linux Users

Hi all,
I've created a new Google Chrome extension to enable the functionalities of .dotjs and .dotcss extensions for Arch Linux users.
Check it here; https://github.com/azer/.w3
Contributions and ideas are welcome,
Azer

Thanks for doing this, never heard of dotjs before, but I love the idea and definitely have some use cases for this.
Of course as an arch user, Im just kindly asking if you plan to create an AUR - package for this?

Thanks for Arch Linux

I am a huge fan of GNU/Linux and have been since the mid 90's, and I just want to say thank you for Arch Linux. My GNU/Linux history started with Red Hat, and then Slackware, then ultimately Gentoo Linux. I have been a Gentoo Linux fan for many years (since it's beginnings), and to be honest, Arch Linux is just as fast and in some cases faster than Gentoo Linux.
The install for me as a first time user to Arch Linux, was very VERY simple, and straight forward. I love the idea of it being installed at the absolute minimum, and I having the option to chose which optional packages are and are not installed from the get-go.
As stated, which this distrobution of GNU/Linux there is no need to compile from source, as Arch Linux is very fast already; for me and my computer anyway.
Again, thanks for this great and powerful GNU/Linux distro.

StackExchange site for Arch Linux?

Do you think there should be a StackExchange site for Arch Linux?
Here is a proposal: http://area51.stackexchange.com/proposa … oAgfiVLGw2.
You probably all know StackExchange. If not, have a look here: http://stackexchange.com/

There is already Unix & Linux: I doubt very much they would be interested in an Arch variant...
Unlike Ask Ubuntu, there is nothing particularly significant about Arch except that we encourage competent users and we already have an excellent wiki.

Win32 loader for Arch Linux?

Hi all,
Do you know any project like the win32 loader of Debian/Ubuntu for Arch Linux is on-going?
I am really interesting to install Arch Linux this way on my Windows laptop, than to use VMware or VirtualBox.

Pajaro wrote:what is win32 loader?
It is a program (.exe file) on Windows to let you install Debian(or Ubuntu) Linux inside Windows without modifying your disk partitions. Actually, the installed Linux image is a file on Windows filesystem, and you can boot into it via the boot menu of GRUB.

Please suggest me good links for locking mechanism in SAP

Please suggest me good links for locking mechanism in SAP
thanks,

Hi Akash,
Here is a small description on lock object.
The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table.
Access by more than one user can be synchronized in the following ways:
Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
Check out this thread:
LOCK OBJECT?

Please suggest best GUI client for Linux setup?

HI,
I need to setup OBIEE 11g on Linux. Please suggest best GUI client to connect to linux and setup OBIEE.
appreacite for your help.
Thanks
Jay.

Hi Jay,
You can use Xming server for linux. I have downloaded Xming server 6.9.0.31. It worked well with Windows XP(32 bit) as well as Windows 7(32 bit). I have used it for Oracle HTTP Server installation and OBIEE 11g installation
After installing, to start Xming go to command prompt and start. This invokes the Xming application properly when compared to double click starting.Go to cmd. Go to location C:\Program Files\Xming Enter this
Xming.exe :0 -clipboard -multiwindow -ac.
Note: colon zero ended up in a smiley!
You will see Xming popup in your right side. Go to putty session and export your display with this command.
export DISPLAY=172.45.62.143:0.0
Replace the ip address with your system ip address. The above one is example.
Note: If your putty session is in client network, use the ip address that is in Ethernet: client server.
Test if display is exported properly with this clock command which gives a GUI popup of clock.
xclock &
Hope this helps.
Regards,
Amrutha.

System encryption using LUKS and GPG encrypted keys for arch linux

Update: As of 2012-03-28, arch changed from gnupg 1.4 to 2.x which uses pinentry for the password dialog. The "etwo" hook described here doesn't work with gnupg 2. Either use the openssl hook below or use a statically compiled version of gnupg 1.4.
Update: As of 2012-12-19, the mkinitcpio is not called during boot, unless the "install" file for the hook contains "add_runscript". This resulted in an unbootable system for me. Also, the method name was changed from install () to build ().
Update: 2013-01-13: Updated the hook files using the corrections by Deth.
Note: This guide is a bit dated now, in particular the arch installation might be different now. But essentially, the approach stays the same. Please also take a look at the posts further down, specifically the alternative hooks that use openssl.
I always wanted to set up a fully encrypted arch linux server that uses gpg encrypted keyfiles on an external usb stick and luks for root filesystem encryption. I already did it once in gentoo using this guide. For arch, I had to play alot with initcpio hooks and after one day of experimentation, I finally got it working. I wrote a little guide for myself which I'm going to share here for anyone that might be interested. There might be better or easier ways, like I said this is just how I did it. I hope it might help someone else. Constructive feedback is always welcome
Intro
Using arch linux mkinitcpio's encrypt hook, one can easily use encrypted root partitions with LUKS. It's also possible to use key files stored on an external drive, like an usb stick. However, if someone steals your usb stick, he can just copy the key and potentially access the system. I wanted to have a little extra security by additionally encrypting the key file with gpg using a symmetric cipher and a passphrase.
Since the encrypt hook doesn't support this scenario, I created a modifed hook called “etwo” (silly name I know, it was the first thing that came to my mind). It will simply look if the key file has the extension .gpg and, if yes, use gpg to decrypt it, then pipe the result into cryptsetup.
Conventions
In this short guide, I use the following disk/partition names:
/dev/sda: is the hard disk that will contain an encrypted swap (/dev/sda1), /var (/dev/sda2) and root (/dev/sda3) partition.
/dev/sdb is the usb stick that will contain the gpg encrypted luks keys, the kernel and grub. It will have one partition /dev/sdb1 formatted with ext2.
/dev/mapper/root, /dev/mapper/swap and /dev/mapper/var will be the encrypted devices.
Credits
Thanks to the authors of SECURITY_System_Encryption_DM-Crypt_with_LUKS (gentoo wiki), System Encryption with LUKS (arch wiki), mkinitcpio (arch wiki) and Early Userspace in Arch Linux (/dev/brain0 blog)!
Guide
1. Boot the arch live cd
I had to use a newer testing version, because the 2010.05 cd came with a broken gpg. You can download one here: http://releng.archlinux.org/isos/. I chose the “core“ version. Go ahead and boot the live cd, but don't start the setup yet.
2. Set keymap
Use km to set your keymap. This is important for non-qwerty keyboards to avoid suprises with passphrases...
3. Wipe your discs
ATTENTION: this will DELETE everything on /dev/sda and /dev/sdb forever! Do not blame me for any lost data!
Before encrypting the hard disc, it has to be completely wiped and overwritten with random data. I used shred for this. Others use badblocks or dd with /dev/urandom. Either way, this will take a long time, depending on the size of your disc. I also wiped my usb stick just to be sure.
shred -v /dev/sda
shred -v /dev/sdb
4. Partitioning
Fire up fdisk and create the following partitions:
/dev/sda1, type linux swap.
/dev/sda2: type linux
/dev/sda3: type linux
/dev/sdb1, type linux
Of course you can choose a different layout, this is just how I did it. Keep in mind that only the root filesystem will be decrypted by the initcpio. The rest will be decypted during normal init boot using /etc/crypttab, the keys being somewhere on the root filesystem.
5. Format and mount the usb stick
Create an ext2 filesystem on /dev/sdb1:
mkfs.ext2 /dev/sdb1
mkdir /root/usb
mount /dev/sdb1 /root/usb
cd /root/usb # this will be our working directory for now.
Do not mount anything to /mnt, because the arch installer will use that directory later to mount the encrypted root filesystem.
6. Configure the network (if not already done automatically)
ifconfig eth0 192.168.0.2 netmask 255.255.255.0
route add default gw 192.168.0.1
echo "nameserver 192.168.0.1" >> /etc/resolv.conf
(this is just an example, your mileage may vary)
7. Install gnupg
pacman -Sy
pacman -S gnupg
Verify that gnupg works by launching gpg.
8. Create the keys
Just to be sure, make sure swap is off:
cat /proc/swaps
should return no entries.
Create gpg encrypted keys (remember, we're still in our working dir /root/usb):
dd if=/dev/urandom bs=512 count=4 | gpg -v --cipher-algo aes256 --digest-algo sha512 -c -a > root.gpg
dd if=/dev/urandom bs=512 count=4 | gpg -v --cipher-algo aes256 --digest-algo sha512 -c -a > var.gpg
Choose a strong password!!
Don't do this in two steps, e.g don't do dd to a file and then gpg on that file. The key should never be stored in plain text on an unencrypted device, except if that device is wiped on system restart (ramfs)!
Note that the default cipher for gpg is cast5, I just chose to use a different one.
9. Create the encrypted devices with cryptsetup
Create encrypted swap:
cryptsetup -c aes-cbc-essiv:sha256 -s 256 -h whirlpool -d /dev/urandom create swap /dev/sda1
You should see /dev/mapper/swap now. Don't format nor turn it on for now. This will be done by the arch installer.
Important: From the Cryptsetup 1.1.2 Release notes:
Cryptsetup can accept passphrase on stdin (standard input). Handling of new line (\n) character is defined by input specification:
if keyfile is specified as "-" (using --key-file=- or by positional argument in luksFormat and luksAddKey, like cat file | cryptsetup --key-file=- <action> ), input is processed
as normal binary file and no new line is interpreted.
if there is no key file specification (with default input from stdin pipe like echo passphrase | cryptsetup <action> ) input is processed as input from terminal, reading will
stop after new line is detected.
If I understand this correctly, since the randomly generated key can contain a newline early on, piping the key into cryptsetup without specifying --key-file=- could result in a big part of the key to be ignored by cryptsetup. Example: if the random key was "foo\nandsomemorebaratheendofthekey", piping it directly into cryptsetup without --key-file=- would result in cryptsetup using only "foo" as key which would have big security implications. We should therefor ALWAYS pipe the key into cryptsetup using --key-file=- which ignores newlines.
gpg -q -d root.gpg 2>/dev/null | cryptsetup -v -–key-file=- -c aes-cbc-essiv:sha256 -s 256 -h whirlpool luksFormat /dev/sda3
gpg -q -d var.gpg 2>/dev/null | cryptsetup -v –-key-file=- -c aes-cbc-essiv:sha256 -s 256 -h whirlpool -v luksFormat /dev/sda2
Check for any errors.
10. Open the luks devices
gpg -d root.gpg 2>/dev/null | cryptsetup -v –-key-file=- luksOpen /dev/sda3 root
gpg -d var.gpg 2>/dev/null | cryptsetup -v –-key-file=- luksOpen /dev/sda2 var
If you see /dev/mapper/root and /dev/mapper/var now, everything is ok.
11. Start the installer /arch/setup
Follow steps 1 to 3.
At step 4 (Prepare hard drive(s), select “3 – Manually Configure block devices, filesystems and mountpoints. Choose /dev/sdb1 (the usb stick) as /boot, /dev/mapper/swap for swap, /dev/mapper/root for / and /dev/mapper/var for /var.
Format all drives (choose “yes” when asked “do you want to have this filesystem (re)created”) EXCEPT for /dev/sdb1, choose “no”. Choose the correct filesystem for /dev/sdb1, ext2 in my case. Use swap for /dev/mapper/swap. For the rest, I chose ext4.
Select DONE to start formatting.
At step 5 (Select packages), select grub as boot loader. Select the base group. Add mkinitcpio.
Start step 6 (Install packages).
Go to step 7 (Configure System).
By sure to set the correct KEYMAP, LOCALE and TIMEZONE in /etc/rc.conf.
Edit /etc/fstab:
/dev/mapper/root / ext4 defaults 0 1
/dev/mapper/swap swap swap defaults 0 0
/dev/mapper/var /var ext4 defaults 0 1
# /dev/sdb1 /boot ext2 defaults 0 1
Configure the rest normally. When you're done, setup will launch mkinitcpio. We'll manually launch this again later.
Go to step 8 (install boot loader).
Be sure to change the kernel line in menu.lst:
kernel /vmlinuz26 root=/dev/mapper/root cryptdevice=/dev/sda3:root cryptkey=/dev/sdb1:ext2:/root.gpg
Don't forget the :root suffix in cryptdevice!
Also, my root line was set to (hd1,0). Had to change that to
root (hd0,0)
Install grub to /dev/sdb (the usb stick).
Now, we can exit the installer.
12. Install mkinitcpio with the etwo hook.

This hook allows for an encrypted root device with support for gpg encrypted key files.
To use gpg, the key file must have the extension .gpg and you have to install gpg and add /usr/bin/gpg
to your BINARIES var in /etc/mkinitcpio.conf.
HELPEOF
Edit /mnt/etc/mkinitcpio.conf (only relevant sections displayed):
MODULES=”ext2 ext4” # not sure if this is really nessecary.
BINARIES=”/usr/bin/gpg” # this could probably be done in install/etwo...
HOOKS=”base udev usbinput keymap autodetect pata scsi sata usb etwo filesystems” # (usbinput is only needed if you have an usb keyboard)
Copy the initcpio stuff over to the live cd:
cp /mnt/lib/initcpio/hooks/etwo /lib/initcpio/hooks/
cp /mnt/lib/initcpio/install/etwo /lib/initcpio/install/
cp /mnt/etc/mkinitcpio.conf /etc/
Verify your LOCALE, KEYMAP and TIMEZONE in /etc/rc.conf!
Now reinstall the initcpio:
mkinitcpio -g /mnt/boot/kernel26.img
Make sure there were no errors and that all hooks were included.
13. Decrypt the "var" key to the encrypted root
mkdir /mnt/keys
chmod 500 /mnt/keys
gpg –output /mnt/keys/var -d /mnt/boot/var.gpg
chmod 400 /mnt/keys/var
14. Setup crypttab
Edit /mnt/etc/crypttab:
swap /dev/sda1 SWAP -c aes-cbc-essiv:sha256 -s 256 -h whirlpool
var /dev/sda2 /keys/var
15. Reboot
We're done, you may reboot. Make sure you select the usb stick as the boot device in your bios and hope for the best. . If it didn't work, play with grub's settings or boot from the live cd, mount your encrypted devices and check all settings. You might also have less trouble by using uuid's instead of device names. I chose device names to keep things as simple as possible, even though it's not the optimal way to do it.
Make backups of your data and your usb stick and do not forget your password(s)! Or you can say goodbye to your data forever...

I'm trying to run my install script that is based on https://bbs.archlinux.org/viewtopic.php?id=129885
Decrypting the gpg key after grub works, but then "Devce root already exists." appears every second.
any idea ?

# 1. The Archboot installation image might have an out of date kernel
# (currently the case) which results in problems when chrooting
# into the install mount point to modprobe efivars. So we use the
# package snapshot on the Archboot media to ensure our kernel is
# the same as the one we booted with.
# 2. Ideally we'd source all local then, but some critical items,
# notably grub2-efi variants, aren't yet on the Archboot media.
