I agree, it's fine to do it that way. An alternative to running the
scan-scripts and invoke something itself, may be to synthesize events
by reading sysfs and pass them as an event to the daemon which will
handle it.
That way it would be very similar to event-replay and would use the same
rules as the normal event. Also events would run in parallel managed by
udevd.
That may be a nice fallback if the events from initramfs are not
available, but similar in operation. What do you think?
