Heh, works for me like charm! Thank you very much, Ingo, for the excellent
job!

It has hanged once (the first time I tried to boot it), while starting either
postfix or cron (AFAIR), but I haven't been able to get any trace and I can't
reproduce this. I'm using the serial console just in case right now. I'll
give it a run in production tomorrow.

I'm attaching the output of dmesg in case you want to know what the system is.

Greets,
RJW
