2011-06-18[archiso] Use dm-snapshot instead of aufs2 (A.K.A. "The Big Commit")Gerardo Exequiel Pozzi
* Use device mapper + snapshot module, instead union layer filesystem. * A block-level approach vs vfs-level. * No more unofficial (Linux) things. * More memory is needed. * Refactor mkarchiso. * Refactor hooks/archiso. * Fix install/archiso_pxe_nbd (due recent change in mkinitcpio-0.6.15 on checked_modules()/all_modules()) [Thanks Dave for the improved workaround] * New configs/releng to build official images. * Works with a Bash script instead of Makefile. (better control and easy to maintain) * Remove configs/syslinux-iso. * Remove archiso2dual script. Integrate functionality in configs/releng. * New configs/baseline to build the most basic live medium or use as template. * New README (draft). [Thanks Dieter for fixing english grammar] Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2011-05-07[archiso] Update fstab and "source dev" of aufs.Gerardo Exequiel Pozzi
* Change from none -> union (looks like util-linux is confused BUG?) Avoid the message: "umount aufs failed: not found" at shutdown. #1 mount -t tmpfs none /something #2 mount -t tmpfs xxxx /something The output of findmnt -rnu -o SOURCE will be blank in #1. * Change from aufs -> auto, make its more generic. * Update devpts and shm entries.

Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-12-07[archiso] Add support to mount iso in loopback mode.Gerardo Exequiel Pozzi
Add two parameters: img_dev=/dev/sdNM where /dev/sdNM is the device where .iso is located. img_loop=/path/to/arch.iso where /path/to/arch.iso is the full path of the .iso in the device img_dev. Original idea from Baurzhan Muftakhidinov. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-11-30[archiso] Add -D <install_dir> option to mkarchisoGerardo Exequiel Pozzi
-D <install_dir> allow to select install directory on target media defaults to "arch". There is a new %INSTALL_DIR% macro for syslinux.cfg. This is how ISO will look now: /syslinux only syslinux related files (syslinux.cfg, *.c32, etc) /arch/ isomounts + *.sqfs images /arch/boot/ Linux + initramfs + Memtest86+ + other files for early boot stage Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-10-17Do not unset archisobasedir when it's setThomas Bächler
This was wrong and can never have worked. Fix it.
2010-10-12[archiso] Update nbd hook to match newer nbd operation mode.Gerardo Exequiel Pozzi
Newer nbd-server uses config file instead of parameters via cmd line (deprecated). Also does not use a fixed port (oldstyle). Sample nbd-server.conf that works with this change: -- CUT HERE -- [generic] [archiso] readonly = true exportname = /tmp/archlinux.iso -- CUT HERE -- Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-07-13[archiso_pxe_nbd] Remove unneeded umount commandsGerardo Exequiel Pozzi

2010-07-09Rename directories and parameteres to be more descriptiveGerardo Exequiel Pozzi
* squashfs images that will be part of read-only branchs for union mount in / are mounted on /ro_branch/{image_name} instead of /tmpfs/mnt/{image_name} (and avoid empty dirs on live env under /mnt) * tmpfs that will be part of read-write branch for union mount in / is mounted on /rw_branch instead of /tmpfs * tmpfs that is for store *.sqfs images when copytoram=y, is mounted on /copytoram instead of /tmpfs.sqfs * tmpfs_size= parameter renamed to rw_branch_size= * tmpfs_sqfs_size= parameter renamed to copytoram_size= Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2010-07-08archiso hook: umount /bootmnt if copytoram=yGerardo Exequiel Pozzi
More generic way than current method, and fix if logic (inverted). Takes the same actions independent of medium (disk/cdrom). Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2010-06-04Add optional command line parameter: archisobasedirThomas Bächler
When remastering the image onto a USB volume, you might want to reuse an existing partition without filling the root with lots of archiso files. The archisobasedir parameter allows to specify a new root directory, isomounts and all images will be searched in this directory.
2010-03-21[archiso] Add support to setups with more than one network card.Gerardo Exequiel Pozzi
Otherwise archiso_pxe_nbd hook can configure the incorrect network card, because ipconfig will configure all interfaces available. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-03-18[archiso] Use a mount handler in archiso_pxe_nbd hookGerardo Exequiel Pozzi
* Register a mount_hook if booted via PXE. This allows to do all needed steps before and after calling archiso_mount_handler. * umount and disconnect network device if copytoram=y Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2010-03-17[archiso] Add nbd hook, to make posible boot archiso from PXE via a NBD.Gerardo Exequiel Pozzi
nbd (network block device utilities) package is required. This package is in AUR at this moment: http://aur.archlinux.org/packages.php?ID=9691 Also mkinitcpio-nfs-utils is required for ipconfig. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-03-16Remove archiso_early hook, use /dev/disk/by-label/${archisolabel} instead.Gerardo Exequiel Pozzi
Takes the advantage of already symlinks created on /dev/disk/by-label/ by 60-persistent-storage.rules add by udev hook. Tested on: * Real machine as CD-ROM and USB key drive. * KVM as CD-ROM and DISK (for both modes, in combination with IDE and SCSI) * VirtualBox as IDE CD-ROM. IMPORTANT note: Since isohybrid is a hack, if more partitions are added to USB key drive, filesystem on these partitions MUST have LABEL, otherwise USB key will fail to boot. Anyway there is an option archisodevice=, to force and specific device where live-media reside. (Maybe isohybrid will change the hack method used in a future) More info at: http://mailman.archlinux.org/pipermail/arch-releng/2010-March/000890.html http://mailman.archlinux.org/pipermail/arch-releng/2010-March/000913.html Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2010-03-01Split aufs mount command from _mnt_squashfs()Gerardo Exequiel Pozzi
New function _mnt_aufs(). Don't display incorrect message (Adding new aufs...) when no aufs branch is mounted, because mount type is bind. Also, makes the code more clean :) Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2010-03-01Welcome back copytoram= optionGerardo Exequiel Pozzi
Fixes FS#17182: copytoram=y does not work with aufs The solution is simple, just use a directory outside aufs tree. * If copytoram=y, then another tmpfs is mounted but on /tmpfs.sqfs * Add a new option: tmpfs_sqfs_size= (default to 75%) * Lock cdrom drive is not locked if copytoram=y Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2009-11-17Rename ramdisk_size parameter to tmpfs_size to avoid conflictGerardo Exequiel Pozzi
Rename ramdisk_size parameter to tmpfs_size to avoid conflict with the kernel parameter that is for old ramdisk based blockdevs (/dev/ramN) and confusion to users. The kernel parameter ramdisk_size=N is in "N * k size", while tmpfs size=N is in "N * [ k | m | g ] byte size" or "in N% of RAM", like is used by default on archiso. This parameter is used only for tmpfs in size option. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2009-10-26Support custom isomounts in archiso hook.Gerardo Exequiel Pozzi
Implement this feature request: FS#16835 - isomounts file whithin archiso hook is inflexible Add an optional "isomounts" kernel command line parameter. In this way, can have differents combinations of kernels/ramdisk/filesystems.sqfs on the same media. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2009-08-25Added vfat support to mount /dev/archisoGerhard Brauer
fstype from klibc don't detect a vfat formatted blockdevice when try to mount /dev/archiso to /bootmnt. Some users don't use the recommened method with dd to bring the image to their USB stick. If they for ex. use Unetbootin to put the iso image on their (v)fat formatted stick they got lost with a kernel panic cause fstype won't detect vfat, so the mount and the later squashfs bindings traps.

2009-01-24Advanced USB delay handlingAaron Griffin
USB boot delay is now handled with the usbdelay kernel param (default=0) We use the built in delay of usb-storage to control this. by setting the module's delay param. If your USB device doesn't work on first boot, try setting usbdelay=10 or so Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
2009-01-24Add a manual sleep and rootdelayAaron Griffin
It seems udev trigger/settle doesn't do what we expect, so we'll add functionality for the rootdelay param back in here. This should help fix FS#12896 Original-idea: Gerhard Brauer <gerbra@archlinux.de> Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
2008-12-23Fix the way squashfs mountpoints are handledAaron Griffin
This is a hacky way to mount squashfs images at directories other than the root. We mount the image to a loop device and then bind it to another directory. This technically supersedes the 'bind' image type, so that should be removed... Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
