I updated my secondary DNS server from 5.3 to 5.4 today.  After the
update, named would not start.  A bit of investigation found that all of
the files in /var/named/chroot/var/named/data had been turned into links
to themselves!

Fortunately, since this is a secondary DNS, all I had to do was delete
the files, replace the root hints file and let everything else copy back
over from the master.  If this had been the master, I would have had to
restore from backups.

Has anyone else seen this problem?
