Useful for debugging (what happened during early boot).
Also useful for distro installers, which can import the early config into
their own environment early after starting:
chzdev --import /run/zdev.initrd.config --persistent --yes \
--no-root-update --force --verbose
After that, distro installers can modify/add the device config based
on interactive or unattended installation choices using
chzdev --enable --active --persistent ...
Finally, distro installers can likewise transfer the entire device config
to the installed system mounted under $SYSROOT:
chzdev --export /tmp/zdev.config --all --type --persistent --verbose

# HAVE_DRACUT

|
|
# This install time parameter determines whether the zdev dracut module is
|
|
# installed (HAVE_DRACUT=1) or not (default). When installed, the module
|
|
# performs the following functions when dracut is run:
|
|
#
|
|
# - copy the persistent root device configuration to the initial ram disk
|
|
# - install a boot-time hook to apply firmware-provided configuration data
|
|
# to the system
