Hello Patrick, thanks again. Yes, label is switched. Yes there really
are stuff on the partitions. No, I dont boot from da0s1d. It is a disk
for migration. But the one who partitioned was fooled by Sysinstall
which creates the first label on extra disks as 'd' and the last from
the allowed 7 as 'a'. Therefore this server is still booting on the
original disk (ad6s1a) and everything else is mounted in the new one
(da0s1), everything but root.
