Recently when upgrading to SVR3.1.2 on codas, I restored the two integral
disks from backup tapes that were two days old. The other two (expansion)
disks didn't need restoring since they weren't repartitioned.

USENET was on one of those disks.

Since the backups I restored from were a couple of days old (weekend), that
meant that I had to bring the "history" file back up to sync with what was
currently on disk by running a rebuild, no big deal.

The "Gotcha!" came when I realized that postings being made by local users
were being thrown away as duplicates! It quickley became evident that the
"seq" (Local article number sequence file, used for the Article-ID) file
was two days old.

New postings would use an Article-ID that was already in the history file,
and be discarded as duplicates, with no error messages other than what's
put in the log file!

Watch out for this gotcha!
