 Hi Ulf,
 
 I don't have that exact box available, but here's another box where I
 implemented the same workaround.
 
 # mount
 /dev/ad2s1a on / (ufs, local)
 devfs on /dev (devfs, local)
 /dev/ad2s1e on /home (ufs, local, soft-updates)
 /dev/concat/nsm on /nsm (ufs, local)
 /dev/ad2s1f on /tmp (ufs, local, soft-updates)
 /dev/ad3s1d on /tmp2 (ufs, local, soft-updates)
 /dev/ad2s1d on /usr (ufs, local, soft-updates)
 /dev/ad2s1g on /var (ufs, local, soft-updates)
