Make rd.udev.debug work in systemd-based initrds

dtardon commented 10 months ago

This makes rd.udev.debug work in systemd-based initrds too.

Changes

A systemd generator is added that sets log level of systemd-udevd.service to debug if rd.udev.debug is present on the kernel command line.

Note

rd.udev.info is ignored as that's the default log level of udevd. The existence of this option makes some sense in the legacy init.sh, as it sets the log level of udevd to err by default, but I don't think we want to go this way...

Lint error :-)

Oops, sorry. Apparently I wasn't fully awake yet when I tried this in the morning... The option is handled (in modules.d/98dracut-systemd/dracut-cmdline.sh), I just didn't find it.
