It's starting to make sense now.. Mounting ufs:/dev/ad*a*2s1a i.o. from
ufs:/dev/ad2s1a simply doesn't work because as I've put in my original
post with # ls -l /dev/ad* it doesn't exist.. Only ad2,ad2s1 & ad2s1a do..

 Which boot device..? I wish it was simple..

The preferred method nowadays is to label the partitions, so probably

To change an active filesystem it must be downgraded to read only or
to unmounted.. [Which I've done with # mount -r -f..]

# tunefs: /dev/ad2s1a: failed to write superblock..

I've updated the /etc/fstab with the ROOT label but I can't get the
single-user mount nor the tunefs to work..

E.
