The kernel has an odd way to handle `"` surrounded parameters.
To handle the parameters as the kernel would do, no simple shell script
suffices, so a new utility `dracut-util` is introduced. Written in "C"
it handles `dracut-getarg` and `dracut-getargs` as the old shell script
functions `_dogetarg` and `_dogetargs` would.
Try to make mksquashfs follow --compress option if squash module is
included, if not specified or invalid, fall back to use mksquashfs's
default compressor.
No function change, decide which compressor to use right before
compressing the initramfs.
This may delay the print of this message:
"dracut: no compression tool available. Initramfs image is going to be big."
but should be OK, this message is not an error.
Simplify the squash mount layout. Instead of overlay on each top
directory (/etc, /usr), just mount and switch_root into the squash
image, with a overlay on top of it.
Also install the binaries and setup scripts separately, so the squash
setup code and the squash image content is independent of each other,
all squash setup script and binaries can be deleted safely upon
switch_root.
With this change, previous squash clean up service and other tricky
implementations are all gone.
This commit depends on systemd commits from:
https://github.com/systemd/systemd/pull/18124
Previouly systemd doesn't recognize non-ramfs initramfs, now this is
doable with SYSTEMD_IN_INITRD=lenient

The squasn mount points are recorded in text file so later clean up
script can umount them, this is not needed, the mount points are fixed
so just detect the umount by hardcoded pattern.
Separately install the modules required for squash image setup.
These modules can be deleted after squash image setup to save
memory.

When a GZIP environment variable is set, this leads to various breakage:
In case 'pigz' is installed and GZIP is defined as a path, e.g.
/usr/local/bin/gzip, then dracut will fail with the following message:
"
pigz: abort: cannot provide files in GZIP environment variable
"
In case 'pigz' isn't installed and regular 'gzip' is used and GZIP is
defined as a path, e.g. /usr/local/bin/gzip, then the path will be
zipped and dracut will fail for no obvious reason. Trying again, dracut
will then fail with following message:
"
gzip: /usr/local/bin/gzip.gz already exists; not overwritten
"
In any case, GZIP environment should be unset to avoid breakage or
unwanted behaviour. This variable is anyway obsolescent, from gzip(1)
manpage.

Before:
```
Benchmark #1: ./skipcpio/skipcpio test-5.10.15-200.fc33.x86_64.img >/dev/null
Time (mean ± σ): 125.5 ms ± 0.9 ms [User: 97.4 ms, System: 27.9 ms]
Range (min … max): 124.8 ms … 129.4 ms 23 runs
```
After:
```
Benchmark #1: ./skipcpio/skipcpio test-5.10.15-200.fc33.x86_64.img >/dev/null

Besides the speedup, skipcpio now parses the cpio header and is not
falsely ending when the early cpio payload contains `TRAILER!!!`.

Adding initial packit [1] support for fedora maintenance which
should automate the release process from upstream release to fedora.

There is no `fstab_lines_l` variable used before.
The `--include` option was turned into `++include` and therefore the
switch option is not reachable anymore.
If SIGWHATEVER will be processed after fsfreeze -f, but before fsfreeze
-u we will end up with /boot/ never unfrozen, let's try to minimize risk of this.
on my system (ThinkPad X201s) I have several modalias entries that are
empty:
/sys/bus/platform/devices/dock.0/modalias
/sys/bus/platform/devices/dock.1/modalias
/sys/bus/platform/devices/dock.2/modalias
executing the drm module setup thus results in the following errors
dracut-install: No SOURCE argument given
when calling dracut_instmods and hostonly mode is enabled.
Skip those entries, as there are no modules to load in this case
anyways.
Note: it is not sufficient to use [['s -s test (file size is greater
than zero), as all those files are 4096B if you stat them.
In the current state, services that depend on network need to
use dracut hooks, since nothing with pull in the network
targets into the transaction.
In the future, it would be nice to provide developers on systemd-only
systems the possibility to not use dracut hooks at all, but simply put
normal systemd services into the initrd.
Also, some modules even right now depend on systemd ordering, like
cryptsetup, so let's make sure, that the ordering inside systemd work
properly as well.
Instead of running directly NM with --debug, create a drop-in in
nm-config.sh. This will make sure, that we can get the debug output
regardless the way how NM will be started.
The current name of this bool is kinda stupid. Based on the manpage
setting it to 0 turns off fcoe, which means that nofcoe=1 should mean
that it is on.
Let's just do the same thing as with rd.lvm=0, rd.luks=0,....
A test of the form
if ! command; then
_ret=$?
...
return _ret
fi
does not capture the return code of `command`, but the negation of the
return code, leaving _ret == 0. The test of this form in inst_multiple
has been refactored to capture and return the right value.
Invalid space broke the creation of the keyboard subdirectories,
leading to a symbolic link
usr/share/consolefonts,consoletrans,keymaps,unimaps ->
/usr/lib/kbd/consolefonts,consoletrans,keymaps,unimaps
in the created initramfs.
With this fix the correct symlinks are created again:
usr/share/consolefonts -> /usr/lib/kbd/consolefonts
usr/share/consoletrans -> /usr/lib/kbd/consoletrans
usr/share/keymaps -> /usr/lib/kbd/keymaps
usr/share/unimaps -> /usr/lib/kbd/unimaps
