2015-12-13add boot params archisoflags= and cow_flags= for mount optionsChristian Hesse
Having files on btrfs subvolumes requires to give mount options. Add boot params archisoflags= and cow_flags= for this purpose. Boot parameters could look like this: ... archisodevice=/dev/sdaX archisoflags=subvolume=isos cow_device=/dev/sdaX cow_flags=subvolume=persist ... Signed-off-by: Christian Hesse <mail@eworm.de>

2015-09-13cleaner boot from loopmounted iso fileAdam Purkrt
Currently, when booting loopmounted iso file, it is necessary to specify not only img_dev and img_loop (which should be sufficient), but also archisolabel or archisodevice. With this patch, archisodevice is directly populated with the correct loop device, and it is not necessary to specify the label when booting from loopmounted iso, which makes for leaner and cleaner grub.cfg.

2015-06-24flush ip addresses after copy to RAMChristian Hesse
We received an IP address from DHCP server and configure it statically. This is required if we continue to use network connectivity to access the root device (for example via NBD or NFS). The lease is not updated, though. This can cause trouble in networks with low lease times. So let's flush the addresses if root filesystem has been copied to RAM. A dhcp client in main system can handle the network connectivity then. Signed-off-by: Christian Hesse <mail@eworm.de>

2015-01-27[archiso] Rename cowfile_size to cow_spacesize=Gerardo Exequiel Pozzi

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>

2014-08-12archiso_pxe_http: Fix location of airootfs.md5Lukas Fleischer
Currently, when booting via HTTP, the airootfs.md5 file is downloaded to /run/archiso/bootmnt/arch/. However, the checksum file is later assumed to be located at "/run/archiso/bootmnt/arch/${arch}". Fix the _curl_get invocation and directly place the file in the right directory. Fixes a regression introduced in commit 5506e1e ([archiso] Rework checksum function, 2014-06-28).

Among other things, 0bb94de ([archiso] Drop aitab support, 2014-06-28) removed the possibility to manually set a specific architecture by using kernel parameters. This, however, is useful, e.g. when installing Arch Linux on a device that reports itself as i586 but works fine with the i686 flavor. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>

2012-10-13[archiso] Introduce cowfile_size= bootparamGerardo Exequiel Pozzi
If not set, nothing is changed in current behaviour. Since dm-snapshot allows to use as "COW" a file with any size, without caring about the the size of "origin", we can avoid creating a "COW" file of the same size as the "origin". This is really useful, when using as cow_device= a filesystem that is VFAT where sparse files are not supported, so if root-image.fs is 1000M, passing cowfile_size=25% will create a root-image.cow of 250M instead of 1000M.
