2021-04-30Ignore SC3060 in initcpio hookDavid Runge
archiso/initcpio/hooks/archiso_pxe_common: Disable shellcheck's SC3060, as ash is able to do bash-like string replacements.
2021-03-09Support EROFSnl6720
EROFS, like Squashfs, is a read-only file system. It can be used to store airootfs in an image file. Its advantage is the support for POSIX ACLs. EROFS downside is that currently it only supports LZ4 compression (LZMA support is not yet fully implemented). A difference from Squashfs is that, EROFS stores change time (ctime) not modification time (mtime). The reverse is true for Squashfs. Implements https://gitlab.archlinux.org/archlinux/archiso/-/issues/59
2021-03-09archiso/initcpio/hooks/archiso: remove redundant /sfs/ from airootfs mount pointnl6720
Remove /run/archiso/bootmnt directory if nothing is mounted there. An empty directory is just confusing.
2021-01-26archiso_pxe_common: remove resolv.conf before copyChristian Hesse
Booting via PXE we want to keep our DNS configuration. So remove /etc/resolv.conf in new root before copying the current file. Without this systemd-resolved fallback nameservers are used and we see an error message when the root ships a symbolic link to systemd-resolved's stub-resolv.conf: cp: not writing through dangling symlink '/new_root/etc/resolv.conf'

2020-07-29Add license and basic documentationDavid Runge
LICENSE: Add GPL-3.0 license. {{archiso,configs}/*,.editorconfig,.gitlab-ci.yml}: Add SPDX license identifier. Makefile: Add SPDX license identifier. Install the `run_archiso.sh` script as global executable `run_archiso`. Use -D and -t flags to install to install files more generically (without a previous call to install the directory). README.rst: Add README outlining the project's scope, how to build images from the profiles and how to test. AUTHORS.rst: Add list of all direct contributors to the repository. CONTRIBUTING.rst: Add basic contribution guidelines, explaining the linter and the license in use. Closes #7 Closes #3
2020-07-17Separate custom comments from shellcheck commentsnl6720
Having a shellcheck directive and custom comments in the same line can trigger SC1107 on old versions of shellcheck.
2020-07-11Adding linting for initcpio scriptsDavid Runge
archiso/initcpio/install/*: Setting bash shebang for all scripts and making them comform with shellcheck. archiso/initcpio/{hooks,script}/*: Setting ash shebang for all scripts and making them comform with shellcheck (for dash, as shellcheck has no ash specific ruleset). Essentially the ash based scripts should be POSIX compliant as much as possible to have an easier time writing, debugging and maintaining them. Ensuring that variables are not treated as options and introducing variable quoting. .gitlab-ci.yml: Integrating shellcheck for initcpio scripts. Closes #32
2018-06-29Remove cow file early for non-persistent systemsv36Christian Hesse
The kernel has an open file handle after setting up the mapping. We can remove it early to make sure it is gone on shutdown. This helps to keep the cow_device clean for non-persistent systems where cow_directory contains a version specific string. 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
The name is more relevant since the usage is shared for both dm-snapshot and overlayfs. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@gmail.com>
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 b3e1d31 ([archiso] Rework checksum function, 2014-06-28).

2014-08-08Reintroduce the possibility to force an architectureLukas Fleischer
Among other things, 36459f3 ([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.
