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
