I just have to enable softupdates on /home, /var, /usr, /usr/obj to
get a panic at "Additional daemons: syslogd" while booting.
If I disable softupdates at /var I'm able to log in (X11) and dial out
-> panic (because of fetchnews/fetchmail/whatever are accessing
something).

How do I do this with _DDB_ (step by step please, I'm not very
experienced with it), I get no core dump? Do I have to boot a
debug-kernel?
