2011-10-23[archiso] Add archiso_shutdown hook.Gerardo Exequiel Pozzi
STATUS: Working (std boot, loop_mnt, pxe) with copytoram=[y|n]. NEEDS: initscript > 2011.07.3, mkinitcpio > 0.7.2, mkinitcpio-busybox > 1.18.5-1 Purpose: we need this for propertly unmount $cow_device, used for persistent dm-snapshot devices. This hook is based on work from Tom Gundersen[#1], but adapted for archiso things (specially the shutdown script) [#1] http://mailman.archlinux.org/pipermail/arch-projects/2011-July/001549.html [#2] http://projects.archlinux.org/initscripts.git/commit/?id=1fa7b4b453e96533ae1db3630031285e5fc302b3 [#3] http://mailman.archlinux.org/pipermail/arch-projects/2011-August/001749.html Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2011-10-23[archiso] Add support for img_label= and allow img_dev same as cow_devGerardo Exequiel Pozzi
* Support img_label= * Allow use img_dev= as cow_device= * Use new function _mnt_dev() from archiso. * Check for error while setting loopback device. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2011-10-23[archiso] Mount all fs on /run/archiso instead of /Gerardo Exequiel Pozzi
This allow to take control again of these mountpoints outside initramfs. (i.e: on deinitramfs stage at shutdown for unmount it) Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2011-10-23[archiso] Allow persistent cow dm-snapshots.Gerardo Exequiel Pozzi
Add some options to control where all COW files will be located. Until this moment all files are located in a tmpfs filesystem. Now is posible to set a device via a filesystem label or device node plus a directory, where all these files will be stored. All dm-snapshot devices will be persistent by default, but this can be changed if wanted. Take care, a filesystem that does not support sparse files maybe is not the best choice for COW files, because they are created with the same size (is apparent) like the read-only device (the image.fs inside .sfs). Of course sooner or later, depending on use, these files actually end up being as big as the read-only device. KNOW-ISSUE: On shutdown in step "Unmounting Filesystems" will [FAIL], all filesystem except $cow_device, will be unmounted/remounted-ro. For this reason this change needs an archiso_shutdown hook, thats unmount all block devices used by archiso. (Work in progress) Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
2011-10-23[archiso] Add a new function _mnt_dev(), use it for mounting archisodevice.Gerardo Exequiel Pozzi
Separate this code from main mount hook, and make it more generic. _mnt_dev(device, mountpoint, flags) -> wait for device and mount, launch a shell if something goes wrong. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2011-08-30[archiso] Cleanup archiso install hook.Gerardo Exequiel Pozzi
* These files was added during developement stage of dm-snapshot branch of archiso. Never was used, sinse archiso works directly with dmsetup and with device nodes in /dev/mapper/ * Added 11-dm-initramfs.rules to keep dm info about nodes persistent in udev db across initramfs/real-root.

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.

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>

2010-06-04Add 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.
2010-05-16archiso_pxe_nbd: Remove unnecessary/unsupported network modulesThomas Bächler
The archiso_pxe_nbd hook adds all network modules, including ones that are not supported: The hook only supports ethernet devices, so there is no need to add wireless, wimax, ppp, irda and plip modules. Adding the wireless modules had an undesired side effect: The wireless driver was loaded in the initramfs stage, where the required crypto modules were unavailable. This caused the initialization of the wireless devices to fail. This patch removes all network modules except ethernet.

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>
