eh; that's what moderators are for (says the person who is supposed to be
moderating, but mostly shirks that duty and leaves it to others).
My question, is, if you build GNU findutils on your system, do the
-xdev option and the -fstype test work on AFS
I'm sure someone will give this a try and let you know. Also, I bet if we
tried really hard, we could get you access to someplace where you can test
for yourself.
If you are in a mood to test things though, is oldfind's -noleaf
option needed to correctly search AFS filesystems? (without it, find
assumes that directories with a link count of 2 have no
subdirectories).
Without testing, yes, it is needed at least some of the time. That
assumption is not valid in AFS, and neither is the assumption that when you
run out of link count you've run out of subdirectories. The problem here
is that AFS files can be one of four kinds - files, directories, symlinks,
and mount points. A mount point is a reference to the root of another
volume by name or volume ID. Mount points look to clients like
directories, but are not counted in the containing directory's link count,
since they do not in fact contain a link to that directory.
So, to a program like find, there are effectively two kinds of
subdirectories -- those that are included in the link count and those that
are not. You can't tell in advance which kind you'll see, so a heuristic
like checking to see if the rule applies to the first directory you
examine, which probably works fairly well for other filesystems, won't work
with AFS.
