It does error out. A namei fileserver will refuse to start and log an
error message if a vice partition used to be inode. This happens even if
you run "rm -fr *". I had to run mkfs/newfs on my vice partitions in
order to switch formats -- after moving the data off, of course.
on a good note, namei seems to be faster than inode node for vos
operations. The speed-up with ufs logging vs. nologging is worth
switching to namei.
