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.

curl in Fedora recently changed its default CA trust store. The
Fedora package no longer specifies an OpenSSL-format bundle file
during build, and curl itself has been patched to use an NSS
plugin called libnssckbi.so when no bundle file or directory is
specified. There are (at present) two possible providers of the
libnssckbi.so module: the original NSS implementation, which
uses a trust bundle built in at build time, and a compatible
implementation from the p11-kit project, which reads a trust
bundle at run time. So if we find a string in libcurl.so that
suggests libnssckbi might be in use, we must both install it and
make an effort to install any trust bundle files it may use.
The p11-kit libnssckbi implementation does include a string that
lists the top-level trust directories it will use, so we try to
find that string, though the best effort I can come up with will
also find many false positives too. To weed out the false
positives, we check whether the matches actually exist as dirs,
and if so, whether they contain some specific subdirectories we
know p11-kit trust dirs must have (thanks, @kaie). For the NSS
libnssckbi implementation, we will likely wind up not finding any
dirs that match the requirements, so we will simply install the
libnssckbi.so file itself, which is the correct action.
This fixes TLS transactions in the initramfs environment when
using a curl that's built this new way; it's significant for
use of kickstarts and update images with the Fedora / RHEL
installer, as these are retrieved in the initramfs environment,
and are frequently retrieved via HTTPS.
use inst() instead of inst_simple()
/etc/pki/tls/certs/ca-bundle.crt is a symlink to
../../ca-trust/extracted/pem/tls-ca-bundle.pem
with inst() we install the original file also.

(cherry picked from commit 1b23c6c65c)
This patch adds bittorrent support to 45url-lib for those that might want
to retrieve the same live image for multiple systems at once without
saturating the network.
This patch requires ctorrent to be installed into initramfs.
Torrent kernel command line format:
root=live:torrent://example.com/liveboot.img.torrent
Start a tracker:
bttrack --bind <tracker_ip> --port 6969 --dfile dstate --reannounce_interval 60
Create the torrent:
ctorrent -t live_image -u http://<tracker_ip>:6969/announce -s live_image.torrent
Seed the initial torrent:
ctorrent live_image.torrent
Boot the live image.
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.
url-lib adds some functions for dealing with URLs (mostly for fetching
files, for the moment).
It uses curl to handle http/https/ftp URLs, but it can be extended by other
modules at runtime by using the "add_url_handler" function.

The livenet module allows you to use a root arg like:
root=live:http://server.name/path/to/live.img ip=dhcp
The named live image will be downloaded with wget and then set up as the
root device.
It currently supports FTP, HTTP, and HTTPS. dracut will try to install
the CA bundle (/etc/ssl/certs/ca-bundle.crt) into the initramfs so that
SSL certificate checking will work properly.
If an HTTPS URL is given and the site fails the certificate check, the
file will be rejected and the system will not boot into it.
