[arch-releng] updates to releng scripts for new dm_snapshot archiso
by Dieter Plaetinck 09 Aug '11

09 Aug '11

Hi, I've been updating the releng scripts for the new archiso (all my changes are in this commit: http://pastie.org/2318603) It seems to build the i686 iso's succesfully, but fails for x86_64 and I have no idea why. I only know `./build.sh all_iso_single` failed (exited >0) in the x86_64 chroot, but it doesn't give me any errors. Could it be because I do a `./build.sh clean_single` and `./build.sh clean_dual` first? (before doing x86_64, after i686). I know you gave instructions at http://mailman.archlinux.org/pipermail/arch-releng/2011-June/001835.html, but they don't mention when exactly i should do which clean commands. Here is the tail of my logfile: [mkarchiso] INFO: Creating SquashFS image for 'work/i686/core-any-pkgs', This may take some time...

[arch-releng] giving archiso block devices more clear names
by Dieter Plaetinck 09 Aug '11

09 Aug '11

Hi, to solve https://bugs.archlinux.org/task/25425 in a robust and clear way, I suggest to - in archiso - prefix all blockdevice filenames with "archiso_". (also, I'm more a fan of underscores then hyphens, in this case it might not matter, but they are usually a bit more robust (like LVM filenames and for variables in bash) so I stick to them for consistency) I.e. /dev/mapper/archiso_lib_modules /dev/mapper/archiso_root_image /dev/mapper/archiso_usr_share Dieter

[arch-releng] [RFC] Inclusion of irc client on the install CD
by Florian Pritz 30 Jul '11

30 Jul '11

Hi, A user just broke her system pretty badly and we agreed that she'll boot a live cd, install irssi and we'd help her fix it. Sadly, installing irssi didn't really work out. I think it would be a good idea to include irssi or weechat (whichever needs less space) on the CD so we can support beginners more easily. I guess it's especially hard (for beginners) to install irssi now because they'll be pretty stressed when their system is broken and the recent perl rebuild probably makes it even worse. -- Florian Pritz

(better control and easy to maintain) * Remove configs/syslinux-iso. * Remove archiso2dual script.

[arch-releng] Call for test: archiso with dm-snapshot
by Gerardo Exequiel Pozzi 18 Jun '11

18 Jun '11

Hello all I want to know opinions about my recent work to archiso, since there are lots of changes. If someone can do some tests, they are very welcomed. Sugestions are very appreciated. Thanks :) TODO: details to current work and archiso2dual. https://github.com/djgera/archiso/tree/dm-snapshot (single commit) (sorry for the grammar, my english is poor) Some highlights: ----- First, aufs2 is not used anymore. The new approach is using device mapper with a snapshot feature, it has some advantages and disadvantages. Basically this is a filesystem image that is read-only associated to a loopback device and another file with an special format (copy on write[COW]) associated to another loopback device. From these two loop dev, a dev-mapper is created, that is writeable. ------ [images] There are three types of images: (*.sqfs renamed to a more standard *.sfs) a) *.sfs: Classic SquashFS compressed images. [no COW used] b) *.fs.sfs: SquashFS with only one file. This file is an image of some filesystem (ext4, ext3, ...). [COW is used] c) *.fs: A filesystem (ext4, ext3, ...) without compressing with SquashFS. Can be useful for doing some test... [COW is used] ------ [aitab] The "isomounts" file is now called "aitab", since a new format is used. #img mnt arch sfs_comp fs_type fs_size img = filename of the image _without_ the extension mnt = mount point of the image arch = architecture of the image (valid options: i686 | x86_64 | any) sfs_comp = SquashFS compression type of the image (valid options gzip | lzo | xz) or "none" if no SquashFS. fs_type = Filesystem of the image (valid options: ext4 | ext3 | ext2 | xfs) or "none" if no filesystem is used. COW mode is only if this is used. fs_size = Total size of the image (absolute value in MiB) or percent of amount of free space (aproximated) in the image (valid values from 1% to 99%). [Ignored if fs_type=none] Of course some options are invalid sfs_comp=none, fs_type=none -------- [initcpio] How archiso hook works now (resume): 1) mount boot device where all images reside 2) mount a tmpfs filesystem to store all cow images (/cowspace) 3) mount all images listed in "aitab" For *.sfs: * assing the image to a loop dev, and mount it. For *.fs.sfs: * assing the image to a loop dev, and mount it to /sfs/$image_name * assing the image inside (*.fs) to a loop dev (A) (ro) * create an empty and sparse file of the same size of the loop dev (A), in the /cowspace * assing that file to a loop dev (B) (rw) * create a dm-snapshot from both loop devs (A) and (B), and mount it to desired location For *.fs * Same as previous without the first step. Note: copytoram does not work with *.fs images (TODO low priority). ------ While in the union mount approach, if "tmpfs" (rw_branch) is full a ENOSPC is reported, and nothing more. In this case, if in the device where the "cow" file reside is full, and you write to the dev-mapper, the system will crash, no ENOSPC is reported. OK? ------- [mkarchiso] NOTE: need an available loop device. (warning when run on chroot created by mkarchroot, since it does not create any loopback device node) * set -e -u * _msg_info and _msg_error functions _show_config => better (more clear) info / error messages :) * Some command line options remove since become obsolete (squashfs compression type, home dir, force) * New command "prepare", make all needed images (except iso). * Filesystem (*.fs) are created with space used plus 10% more (take care (aproximated for most cases) of metadata). * All directories (future images) listed on aitab should exists (aitab is parsed instead of using find) ----------- [configs/releng] (was syslinux-iso) * The build now uses a bash script instead of Makefile, we can take a better control of the build process. * There is no more "overlay" concept like with union mounts, all changes now are merged at build time in root-image. * directory scheme is more "dual-iso" friendly.. * Warning: Do not build net_iso after core_iso! (TODO stop with error) * download-repo.sh discarded, this process is now done in the same build.sh script (can exclude packages listed on a file) * core-pkgs.sfs (mounted at /repo/pkg): core.db + core_$arch_packages + core_any_symlinks (relative ../any/ ) * core-any-pkgs.sfs (mounted at /repo/any): core_any_pkgs * Warning: neither /repo/pkg and /repo/any is writeable (previously /src/... was) * .iso sizes: 382M archlinux-2011.06.14-core-i686.iso 392M archlinux-2011.06.14-core-x86_64.iso 195M archlinux-2011.06.14-netinstall-i686.iso 200M archlinux-2011.06.14-netinstall-x86_64.iso * Directory scheme or core-iso. ??? arch ? ??? aitab ? ??? any ? ? ??? core-any-pkgs.sfs ? ? ??? usr-share.fs.sfs ? ??? boot ? ? ??? i686 ? ? ? ??? archiso.img ? ? ? ??? vmlinuz26 ? ? ??? memtest ? ? ??? memtest.COPYING ? ??? i686 ? ??? core-pkgs.sfs ? ??? lib-modules.fs.sfs ? ??? root-image.fs.sfs ??? syslinux ??? boot.cat ??? *.com ??? *.c32 ??? *.0 ??? hdt ? ??? modalias.gz ? ??? pciids.gz ??? isolinux.bin ??? memdisk ??? splash.png ??? syslinux.cfg ------------- [configs/baseline] * A minimal working profile as example, booteable, just to do tests or use as template for other projects, etc. 145M archlinux-2011.06.14-i686.iso ??? arch ? ??? aitab ? ??? boot ? ? ??? i686 ? ? ??? archiso.img ? ? ??? vmlinuz26 ? ??? i686 ? ??? root-image.fs.sfs ??? syslinux ??? boot.cat ??? isolinux.bin ??? menu.c32 ??? syslinux.cfg -------- Make releng images / how to build: pacman -S devtools --noconfirm --needed mkarchroot /tmp/pichicho base mkarchroot -r bash /tmp/pichicho echo 'Server = ftp://192.168.0.66/archlinux/$repo/os/$arch' >> /etc/pacman.d/mirrorlist #your mirror! pacman -S make git squashfs-tools syslinux devtools cdrkit mkinitcpio-nfs-utils nbd --noconfirm --needed cd /tmp git clone git://github.com/djgera/archiso.git -b dm-snapshot cd archiso/archiso make install cd ../configs/releng/ ./build.sh all_iso #or net_iso | core_iso Enjoy! -- Gerardo Exequiel Pozzi \cos^2\alpha + \sin^2\alpha = 1
