Subject: Deleting advfs quota.* file links

Q: How can I delete a hard-link to quota.user or quota.group?
BKG: I wrote and ran a perl script which made hard-links to files recursively
throughout a directory hierarchy. Unfortunately this also included the
quota.* files at the top of the fileset. I have now inserted a test to stop
this happening again, but the damage is already done.
Once I have these new links to quota.user (let's call it 'uuu') and
quota.group ('ggg') I found that
rm uuu ggg
didn't work (failed noisily) and
rm -f uuu ggg
failed silently.
Looking through the tru64 archives, I see that people have asked several
times about deleting the quota.* files because they looked large and
unneeded, but were always mollified by the info that the files were sparse.
Unfortunately this doesn't help me.
Strangely, I thought I did manage to fix this same problem last week from an
earlier run, but I can't do it today.

SUMMARY
Tru64 doesn't let you delete the quota files at all. Some sort of hook in a
lower level of the AdvFS. Doesn't just recognise the name; you can happily
link to them, and move the links anywhere within the fileset.
unlink is equally ineffective.
Thanks to Bob Harris for the most informative answer. Apparently Tru64
version 5.1b "... is the first version that allows the removal of extra
st_nlink entries for the quota files." I'm running 4.0f I think.
In the end, I have pushed them to the side. I can live with them there. I
feel confident that I could get rid of them by doing a rmfset, but it's not
worth it.
Thanks to Bob, Matthew Wild and John Lanier for your suggestions.
sincerely,
Glen
