WARNING: WITNESS option enabled, expect reduced performance.
Trying to mount root from ufs:/dev/ad0s1a
The kernel boots and the system is usable.
Same with a kernel after Dec. 10th: looks mainly the same, but "root" does not mount because it is not found. The system asks for its root device:
Manual root filesystem specification:
<fstype>:<device> Mount <device> using filesystem <fstype>
eg. ufs:da0s1a
? List valid disk boot devices
<empty line> Abort manual input
mountroot> ?
List of GEOM managed disk devices:
ad0f ad0e ad0d ad0b ad0a acd0 ad0 fd0
shouldn't this list look like:
ad0s1a ad0s1b ad0s1d ad0s1e ad0s1f acd0 ad0 fd0
Looks like kernels after Dec. 10th, 2008 are having problems with the MBR written on disk by kernels before Dec. 10th.
The system is installed on a "Dangerously dedicated disk".
