mkinitcpio is the initramfs generation tool written for Arch Linux.
A new release of mkinitcpio has been tagged. The release can be downloaded from
Gitlab:
https://gitlab.archlinux.org/archlinux/mkinitcpio/mkinitcpio/-/releases/v39
CHANGES WITH v39:
Announcement of future breaking changes:
* The use of global variables for getting the value of cmdline
parameters
is now deprecated. Hook authors should update their hooks to use the
getarg function instead. See mkinitcpio(8) for more information on
getarg's usage. In a future release, global variables will no longer
be
assigned for cmdline parameters.
New Features:
* ARM zImage is now supported. The relevant code paths have also been
cleaned up with more code sharing between the main implementation and
the shell completions.
* install/acpi_override is a new hook that allows ACPI table upgrades
and overrides. It will look for `.aml` files in
`/usr/initcpio/acpi_override/` and `/etc/initcpio/acpi_override/`
which will be copied to `/kernel/firmware/acpi/` in the early
uncompressed initramfs.
Changes in mkinitcpio:
* Compressed files are now placed in the uncompressed early cpio
instead of the compressed cpio. This change ensures we are not double
compressing files.
* As compressed files are included in the early cpio, module
decompression has been disabled by default to avoid compressing
them using a weaker compression and improve boot speed for some
weak CPUs.
* MODULES_DECOMPRESS will now also decompress firmware files.
* The values of arbitrary cmdline arguments can now be retrieved at
runtime
using the getarg function.
* The default umask is now 022 to ensure files installed with hooks have
the permission set to 644 by default.
* gzip is used instead of zstd if the kernel version is below 5.9.
* `add_all_modules_from_symbol` has been fixed to ensure we are not
failing if no symbols can be found.
* `add_file` will now use the source file name if the destination ends
with a slash.
* `add_file` now supports copying from file descriptors. This is useful
for cases where you want to pipe files into the initramfs.
* `add_file_early` and `add_dir_early` has been added to include files
into the early CPIO.
* Include `--no-cmdline` in the help output along with some missing
options in the shell completion.
* UKIs will now be created with `ukify` if it is available on the
system.
Changes in lsinitcpio:
* lsinitcpio now supports listing, analyzing and extracting UKIs.
* It will now provide a count of the number of included modules and
binaries
* Fixed a bug where the `[explicit]` marks in the output was lost.
Changes in hooks:
* install/resume and install/systemd includes the lzo and lz4 kernel
modules to support resuming from hibernation when using a hibernation
image compression algorithm other than the compile-time default.
* install/keyboard now includes all modules under `kernel/hid/*-hid`
directories, which may be required by some keyboards.
* install/keyboard removed a workaround for Linux 3.5.
* install/base now includes the umount binary. This avoids the
mismatch where mount was from util-linux, while umount was provided
by busybox.
* install/lvm2 now includes the dm-vdo module introduced in Linux 6.9.
Changes in packaging:
* The libalpm hook will now rebuild the initramfs when kernel modules
and firmware files are removed.
* mkinitcpio-generate-shutdown-ramfs.service has gotten cleanups and
hardening options enabled. `systemctl soft-reboot` pulls
shutdown.target so the service is now removed from the mentioned
target and included into `poweroff.target`, `halt.target`,
`reboot.target` and `kexec.target`.
* The distributed tarball now uses xz instead of gzip.
* The Makefile now prefers to use asciidoctor if available.
* Presets are now generated when mkinitcpio is installed.
