That isn't true here. If I run /usr/lib/desktop/permissions by hand and try
to do something I shouldn't, it asks me for the root password. There may well
be some way to trick it, but it's not that obvious (especially since I don't
use the thing; it's the boring half of chmod). IRIX 5.3, if it matters.

Cheers,
