I'll change bsdlabel to not ask GEOM_BSD what the MBR
offset is. Instead it'll make the label relative in the
same way the kernel does it. This fixes the "disklabel:
partition c doesn't start at 0!" and "disklabel: An
incorrect partition c may cause problems for standard
The "partition c: partition extends past end of unit"
can be fixed by the kernel in-memory so that you only
have to run "gpart commit /dev/ad8s4" to write it to
the disk. The kernel already does it, but doesn't yet
mark the in-memory label as dirty. You need to make
an unrelated change right now to cause the label to
Unfortunately, there's no quick way to fix "partition
f: partition extends past end of unit" if it's really
larger than the slice size. If the warning is the
result of having an offset of !0, then it'll will be
fixed by fixing bsdlabel to make the label relative
on its own.
