But the whole boot system seems to have changed - this machine
boots incredibly fast now (not that it matters, it's rebooted
at most once in a week). 

Some new info: I get complaints from udev in /var/log/errors.log
about files not being found in /lib/udev/rules.d. This would explain
things I guess. But when I look in /lib/udev/rules.d those files *do*
exist. So maybe things go a bit *too* fast (or out of order). If that
is the case, what can be done about it ?

I have to do a fresh install on 5 new machines (similar HW) later
this week. I guess they will fail as well...

P.S. I also tried udev .172 from AUR, same result.
