2015-04-21explicitly detach loop device on umountChristian Hesse
I see cases where a stale loop device stays around and fills up my partition as image file is still in use and does not get unlinked. Explicitly detach loop device on umount to fix that. Signed-off-by: Christian Hesse <mail@eworm.de>
2015-01-27[archiso] Add optional OverlayFS supportGerardo Exequiel Pozzi
This is the first attemp to test overlayfs in archiso. The current dm-snapshot mode is keep and is enabled by default, while the new mode is enabled via "-s sfs" to mkarchiso. No new boot parameters are added, since archiso hooks detects if the .sfs file is for dm-snapshot (airootfs.img inside) or for overlayfs. Persistence is supported in overlayfs mode using the same options (cowlabel or cowdevice), but warning while in dm-snapshot mode, only one file is used (airootfs.cow), in overlayfs mode internal files for workdir/ and upperdir/ are allocated, so you can not use VFAT or NTFS. To test this, you need to enable [testing] in pacman.conf from releng profile and edit build.sh then add "-s sfs" in make_prepare() Look at: setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -D "${install_dir}" prepare Replace with: setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -s sfs -D "${install_dir}" prepare The build requires just half of space that the build for dm-snapshot, since there is no ext4 img ;) Just to remember: there is no space gain in .sfs (just about 2M) There is at least one thing during boot with machine-id service: Dec 24 03:31:39 archiso systemd-machine-id-commit[183]: Failed to unmount transient /etc/machine-id file in our private namespace: Invalid argument Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@gmail.com>

2014-06-28[archiso] Drop aitab supportGerardo Exequiel Pozzi
Always create one filesystem of a fixed size (32G), format (ext4) and know name "airootfs". Simplify logic a lot.

2014-06-28[archiso] Always use a 32GiB filesystem size for airootfsGerardo Exequiel Pozzi
There is no big overhead. Space usage in ext4-1G is ~0.4M while in ext4-32G is ~4M. Just use a big value to make all people happy.

2011-12-03[archiso] Cleanup: Remove *.fs support.Gerardo Exequiel Pozzi

2011-11-28[archiso] Checksum only aitab and *.sfs (per architecture)Gerardo Exequiel Pozzi
We are currently checksuming all files inside $archisobasedir (aitab, *sfs, kernel/initramfs and boot/syslinux related files) this is stored in one file only. Its works good for now, but I think we only need to checksum only aitab and *.sfs if they are needed. Currently if you boot a dual-iso in i686, also checksum is done for *.sfs of x86_64. Not a big issue, this just take a bit more time. The real issue is when booting via PXE with HTTP/FTP methods, since they download only aitab and needed *.sfs files, can not use directly the only one file where checksums are stored. This patch does: (1) Do not checksum syslinux related files, anyway you are already reach initramfs stage. (2) Do not checksum kernel/initramfs files, for the same as (1) (3) Two checksum.${arch}.md5 for each i686 and x86_64 for only aitab and *.sfs.
