Should TSM consider the change of AIX permissions to be a modification of
the file, and therefore, back it up.  We have a client on an AIX 4.3.3 box
with TSM 3.7.2 where someone (whose mouse has been replaced with a
thumbscrew) did a global change of permissions to 777.  As far as we can
tell by our own tests, this did not cause a backup of every changed file,
so there is no way to do a PIT restore to the way things were, at least
with the present configuration.
