I don't believe there are any, except perhaps some obscure edge cases[1].
Every use for ACLs and extended attributes I've ever seen reduces down to the
sysadmin gaining finer control over what other people can and cannot do on
his system. On a single user work-station, the user IS the sysadmin, so the
point usually becomes moot.

[1] For example, one might want a flag that can be set and unset on a file
depending on the last action taken by some specific software. An archive
attribute used by backup software would be the most well-known example. But
this is certainly not the general case.

The only (more or less common) software I know which states that it runs
better with extended attributes is Beagle. There ought to be some
performance benefits but I've never verified it.

Nope. I didn't complain about. Never heard of until this thread that I
can recall. I haven't complained about gcp, cp or anything that I recall.

Well, I asked the question if star was on the Gentoo live CD. It was
posted that it was not on the CD. I don't know myself so I asked. Then
it was mentioned that I should ask for it to be on the CD when I don't
plan to use star anyway. Since it doesn't matter to me one way or the
other, I thought it may be better for someone who does want it on the CD
to ask rather than me, who doesn't really matter either way.

It is true that you are very helpful with whatever you are familiar
with. Thanks much for that. We all need a little help from time to
time. We all run into that stump sometimes. Heck, I got a big ole
stump in my front yard that I been bumping with the tractor. I think
the ants are doing better than the tractor. o_O They just take a
little longer. lol
