no, rename() supports xattr.
unpatched mv(1) doesn't break xattrs. (it uses rename())
however file copying requires xattr support.
in any event it should be configurable somehow, so if the user doesn't
want xattrs used they won't be.
i was mainly pointing out that filesystems don't have to be rewritten,
and we don't have to switch to HorribleFileSystemPlus from apple to
get resource fork crap, xattrs are here and would work for something
like this, but as you say userland tools are probably not really ready
for such a thing.
