chmod has an interesting story to it.
It is known to work with Darwin 10.3.9 (AFP 3.1), 10.4.2 and 10.5.x (AFP 3.2).
chmod will not work properly in the following situations:
- AFP 2.2, this needs some more verification but I don't see how it is possible
- netatalk 2.0.3 and probably earlier:
. netatalk will only enable it at all if you have "options=upriv"
set for that volume.
. netatalk will never be able to chmod the execute bit and some others on
files; this is hard coded in unix.c's setfilemode() in 2.0.3. It's like
it has 2.2 behaviour even though it is trying to speak 3.1.
. The only bits allowed are
S_IRUSR |S_IWUSR | S_IRGRP | S_IWGRP |S_IROTH | S_IWOTH;
There's probably a reason for this, I don't know what it is.
. afpfs-ng's behaviour's the same as the Darwin client.
The right way to see if a volume supports chmod is to check the attributes
found with getvolparm or volopen, then to test chmod the first time.
