 Naturally the fstab on the upgrade target contains the correct root entry.

 # NetBSD /targetroot/etc/fstab
 /dev/wd0a               /               ffs rw,discard              1 1

 Where was the (real) root disk last mounted and what medium did you boot from?

 Aaahh, that reminds me of the last time with the loop back mounts.

 The root was last mounted in /mnt die disable the raid mounts in 
 /mnt/etc/fstab.

 The install kernel was booted from /dev/wd0a - the root to be upgraded.

 So I need to re-try that with "fixing" /etc/fstab before booting the 
 install kernel and see

 whether sysinst can cope with that then.

 Mount it manually on /targetroot or / once before trying the upgrade, the
 "last mounted on" info (like: dumpfs $disk | fgrep fsmnt) needs to
 look like something that was / before sysinst will autodetect it.

 The "cannot continue" part is stupid, it lacks a manual partition
 selector (SMOP, but tedious).

 You mean install kernel with ramdisk as root? That would do it.

 mounting /dev/wd0a on /targetroot instead of /mnt did the trick - thanks.
