It is now a wreck. Other systems running CURRENT (as of the most recent revision as of today) were partially installed as 12-STABLE/12-CURRENT and "moved on" to what is now 13-CURRENT. They do not(!) indicate such problems reported. Either I hit the crap installing a new system whilst there was a problem, or something really strange happened. The bad thing is that kernel.old exits/dies with an exception and /boot/kernel/ seems to be completely corrupted. Tomorrow I try to install a prepared pkg tar arcive FreeBSD-kernel from aCURRENT pkg base and hope this will fix the issue. Regards, oh - -- O.
