It does not need to, it just scans the whole /var/spool/news tree, and
you now made it an own file system -- which should be fine, but I never
actually tested this, so I never got the idea that texpire would
consider lost+found to be a newsgroup name component. This problem will
then occur ever since we expire groups that are not in groupinfo (which
we must, otherwise, freshly-deleted groups will no longer be expired).

I shall have texpire skip over lost+found or directories it must not
access.

That depends. If you lose files through file system corruption, it
depends on how smart your fsck program is. With modern Linux file
systems (ext3fs, patched reiserfs) with data=ordered or data=journal, or
with BSD softupdates or non-async ffs, such things should never happen
except for power failures that happen while the hard disk has its write
cache switched on -- most ship this way though :-(

No problem.
