Again, I haven't actually tried to do this since very shortly after GEOM
first went into the tree. Based on phk's recent reply, it appears that
the behavior I was seeing then was buggy; at least it would be
considered buggy today.
What I was specifically unable to do was, while running FreeBSD mouted
=66rom ad0s1, delete ad0s2 and ad0s3 and create a new, larger ad0s2. I
even tried to manually update the MBR via dd, thinking perhaps it was
something on the ad0s{2,3} slices that was causing the problem.i In the
end, I was perfectly content to just boot from the boot CD and do it, and
haven't had to do anything of the sort since :)
