dracut:

• allow running on a cross-compiled rootfs

  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.

  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.
