For the shell scripts, new environment variables were introduced.
dracutsysrootdir is the root directory, file existence checks use it.
DRACUT_LDCONFIG can override ldconfig with a different one that works
on the sysroot with foreign binaries.
DRACUT_LDD can override ldd with a different one that works
with foreign binaries.
DRACUT_TESTBIN can override /bin/sh. A cross-compiled sysroot
may use symlinks that are valid only when running on the target
so a real file must be provided that exist in the sysroot.
DRACUT_INSTALL now supports debugging dracut-install in itself
when run by dracut but without debugging the dracut scripts.
E.g. DRACUT_INSTALL="valgrind dracut-install or
DRACUT_INSTALL="dracut-install --debug".
DRACUT_COMPRESS_BZIP2, DRACUT_COMPRESS_LBZIP2, DRACUT_COMPRESS_LZMA,
DRACUT_COMPRESS_XZ, DRACUT_COMPRESS_GZIP, DRACUT_COMPRESS_PIGZ,
DRACUT_COMPRESS_LZOP, DRACUT_COMPRESS_ZSTD, DRACUT_COMPRESS_LZ4,
DRACUT_COMPRESS_CAT: All of the compression utilities may be
overridden, to support the native binaries in non-standard places.
DRACUT_ARCH overrides "uname -m".
SYSTEMD_VERSION overrides "systemd --version".
The dracut-install utility was overhauled to support sysroot via
a new option -r and fixes for clang-analyze. It supports
cross-compiler-ldd from
https://gist.github.com/jerome-pouiller/c403786c1394f53f44a3b61214489e6f
DRACUT_INSTALL_PATH was introduced so dracut-install can work with
a different PATH. In a cross-compiled environment (e.g. Yocto), PATH
points to natively built binaries that are not in the host's /bin,
/usr/bin, etc. dracut-install still needs plain /bin and /usr/bin
that are relative to the cross-compiled sysroot.
The hashmap pool allocate_tile/deallocate_tile code was removed
because clang-analyze showed errors in it. hashmap_copy was removed
because it wasn't used and clang-analyze showed errors in it.
DRACUT_INSTALL_LOG_TARGET and DRACUT_INSTALL_LOG_LEVEL were
introduced so dracut-install can use different settings from
DRACUT_LOG_TARGET and DRACUT_LOG_LEVEL.

Bash 5 apparently longer propagates variable assignments to local variables
in front of function calls when in POSIX mode:
[lkundrak@demiurge ~]$ cat feh.sh
print_VAR () {
echo "$VAR";
}
testfunc () {
local VAR="OLD"
VAR=NEW print_VAR
}
testfunc
[lkundrak@demiurge ~]$ bash4 --posix feh.sh
NEW
[lkundrak@demiurge ~]$ bash5 --posix feh.sh
OLD
[lkundrak@demiurge ~]$ bash5 feh.sh
NEW
[lkundrak@demiurge ~]$
It works the way it did in Bash 4 in non-POSIX mode, for external programs,
or for non-local variables. Don't ask me why -- it's probably some
compatibility thing for some sad old people.
However, this precisely happens when fsck_single() is calling into the
fsck_drv_com(), assigned to _drv by fsck_able(). That ruins the
TEST-70-BONDBRIDGETEAMVLAN test's server and probably more.
Let's pass the fsck driver binary via the function argument instead. It's
less messy anyway.
The needle argument in this specific case is a pattern, which cannot be
matched by the "literal" string matcher strstr.
This can result in fsck calls like:
e2fsck -a -y /dev/sda1
Which will then exit with an error like:
e2fsck: Only one of the options -p/-a, -n or -y may be specified.
Hence, it is necessary to use the strglobin function to correctly match
the pattern.
Just like btrfs, xfs now requires CRC module that cannot be resolved via
normal module resolving.
Move this hack into fs-lib and remove it from btrfs module.

in dracut.conf:
fscks="<tools>"
nofscks="yes"
and similary on command line:
--fscks [LIST] (in addition to conf's, if defined there)
--nofscks

To not pollute dracut-lib.sh, all the fsck related functions were moved
to fs-lib.sh. The functions available are as follows:
- fsck_single
this will detect/verify filesystem, check if it has necessary tools and
check the filesystem respecting additional flags (if any), using
specific "driver" (or falling back to generic one). Currently
available: fsck_drv_{com,xfs,std}. 'com' is used for tools following
typical subset of options/return codes (e.g. ext, jfs), 'std' is used
for "unknown" fs and doesn't assume it can be run non-interactively.
Please see comments around the code for more info.
- fsck_batch
this will check provided list of the devices;
Both of the above functions will fake empty fstab, to make generic fsck
not complain too much (excact devices are always provided on the command
line).
"Known" filesystems currently: ext234, reiser, jfs, xfs
- det_fs
Small bug fixed - as this function is meant to be called in $(), it may
not be verbose.
Current behaviour is:
- if detection is successful, use its result
- if detection is not successful, and filesystem is provided, return
the provided one; otherwise use auto
