Hmmm... After searching through any number of web pages, I must
conclude that background fsck(8) works on all versions of UFS on 5.x.
Conclusion drawn this way because if it didn't it would be documented
as not working, or there would be any number of messages on mailing
lists asking why doesn't it work?  Also, background fsck(8) depends on
the 'snapshotting' feature of UFS, which comes out of the soft-updates
functionality definitely available in both UFS1 and UFS2.

One of these days I really must get my hands on a 5.x system.
