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.

The recent systemd upstream introduced a slightly modified version
string which included information about a git commit, which however
broke the version check in dracut. Unfortunately, the (( )) bash syntax
went along with it in certain cases and introduced a pretty nasty issue,
when the systemd would boot up but with slightly changed environment.
To prevent this from happening in the future, let's at least check if
the version parsed from the `systemd --version` output is a comparable
number.
With hostonly enabled, only modules that are currently
loaded are included in the initrd. Modules which are
explicitly listed in modules-load.d do not need to
be filtered that way. Fix for boo#962224.
systemd sets /proc/sys/kernel/core_pattern to use systemd-coredump.
However, systemd-coredump is missing from initrd, making dumping
the core in initrd impossible by default.
Reference: bsc#1054809
Both 'utmp' and 'root' groups are mentioned in tmpfiles.d/systemd.conf
and as such should be included.
It's probably better to have something equiv to inst_rule_group_owner()
for udev rules which parses out users and groups and adds them to the
passwd/group db respectively.
Could also rely on sysusers but as the initramfs is static in this
sense, it's more efficient to pre-define the users IMO.
If journald.conf already contains Storage=persistent, journald will
write to /var/log/journal/, which ends up at /run/initramfs/log/journal/
after switching root. We want to make sure early boot logs are written
to /run/log/journal/ so they can be flushed to /var/log/journal/ after
switching root.
Basic systemd functionality is in 00systemd now.
Switching root and the initrd.target is in 00systemd-initrd.
Dracut additions to the systemd initrd are in 98dracut-systemd.
During boot systemd tries to load autofs4, but dracut will only
add it if it's loaded by the time dracut is run.
Modify dracut to always load autofs4.

some programs e.g. systemd-journald expect a directory in /var/log as
the marker to do some actions. Here journald tries to flush
/run/log/journal to /var/log/journal, if the directory is seen.
/var/log is now a symlink to /run/initramfs/log.
The rootfs-generator was installed in the wrong path
in the initrd, cause it never to be run.

Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
Systemd tries to load this modules very early.
Even though they are not strictly required it it is a good
thing to have them around.
