It seems the script doesn't mount the nfs, so I'm a bit puzzled about
what it was suppose to check.
In any case, though I don't think it was my original problem (but I
might be wrong), it appears that currently if the nfs is mounted with
"noacl", it might fail with Operation not supported even if the nfs
mount is rw and can be changed directly on the mount.
The attached script reproduces the Operation not supported when trying
to move a file on the aufs (though moving it on the nfs works). It's not
as nice as yours, it prints some stuff, and assumes nfs-kernel-server is
already running.
