 and after a hint from mlelstv I rebooted at this point, again into
 single user. It made no visible difference, as the next step produced
 exactly the same results:

 but now (after the reboot before that tunefs -N) the next steps worked
 as described:
 
 > # mount /
 
 this apparently got rid of the log.
 
 > # mount
 > /dev/wd0a on / type ffs (local)
 
 and now the journal lines are gone:
 
 # tunefs -N wd0a
 tunefs: tuning /dev/rwd0a
 tunefs: current settings of /dev/rwd0a
         maximum contiguous block count 4
         maximum blocks per file in a cylinder group 2048
         minimum percentage of free space 5%
         optimization preference: time
         average file size: 16384
         expected number of files per directory: 64
         quotas disabled
         POSIX.1e ACLs disabled
         NFS4 ACLs disabled
 tunefs: no changes made
 
 and it stays this way after a reboot (I had removed the log option from 
 /etc/fstab before I started trying all this).
