This shows the OS version (from /etc/os-release), e.g. "edge", on the splash
screen. os-release is a tiny text file, adding it to the initramfs doesn't seem
too bad, and having this information on the splash screen can be helpful.
Note that this uses "VERSION" and not "PRETTY_NAME" from the os-release file,
since the splash already shows "postmarketOS" (and the pretty name includes
that too), it seemed redundant and took up valuable display space.
[ci:skip-build]: already built successfully in CI
Enable using the postmarketOS initramfs for boot-testing devices, in
this scenario we don't care about some components like the splash, mdev,
or subpartitions, instead we want to run full udev (to load all devices)
and then run hooks. The ci hook will deadloop after running tests.

With full-fat mdev supporting by-partlabel lookups, there is a small
delay during startup. As mdev and dynamic partitions aren't actually
needed for the framebuffer device, move show_splash earlier.
Furthermore, slightly rework setup_framebuffer to not dump the verbose
message about waiting for the framebuffer unless the framebuffer isn't
found.

Drop in mdev.conf and the /lib/mdev/persistent-storage script, these
cause /dev/disk/by-* to be populated in the ramdisk, making it
possible to do look up partition by-label and by-partlabel for free,
compared to findfs which can take some time.
As a first optimisation based on this, check for some partitions using
these paths and prioritise them when looking for subpartitions. Drop the
first find_boot_partition call as it doesn't really save time over the
call in the while loop.
The mdev config also handles setting up /dev/null, /dev/random, etc, so
these don't have to be done manually.
Mount /dev (and /run) in initramfs so util-linux switch_root can move
the mounts over to the new sysroot before changing root.
BusyBox switch_root doesn't even attempt to move anything so use
util-linux's switch_root for this.
Explicitly disable tests too...
Make it possible to load modules from the file installed by devicepkg-dev,
that will be there when extra modules are needed. This is coded in a
backwards-compatible way, so that it can be independent of the main modules
MR.
The code changes create a new function which takes a list of modules
and possibly a file (that should contain a list of modules too). The
idea is to be able to support also loading modules for initramfs-extra
in the future, and having a similar file would be more convenient than
extracting all the modules each time. In addition, the "[ -d /lib/modules]"
check has been removed. If there's no modules directory, as all
modules might be built-in, modprobe will fail, but that will not be
fatal. This will most likely only exclusively happen in some android
downstream kernel, so it should not be a big concern.
As a preparation for #1836, move the sourcing of deviceinfo to its own
function. This should allow to have a single point in the whole of the
initramfs for the sourcing of the deviceinfo, instead of every script
that needs it sourcing it. This allows to change the way deviceinfo is
sourced in the future with a lot less effort.
This package contains base file and module lists for the initramfs /
initramfs-extra archives, along with the init.sh
The primary reason for doing this is so that changes to these
files/lists can be properly versioned (in pkgver), and (re)building
mkinitfs itself is no longer required for these changes.
- Add base file list for initramfs. The dirs at path
/usr/share/postmarketos-mkinitfs/* are "new" in mkinitfs 2.0
- Install default modules to /usr/share
- Install system config to /usr/share/mkinifs
- Add base files for -extra archive
- Create user config dirs
- Update hook dirs in init.sh, change from mkinitfs 2.0
- Remove splash images, obsolete since pbsplash
- Support uncompressed initramfs-extra
