Ignoring file permissions on removable, user-supplied media sounds like
something that ought to be done above the level of individual
filesystems, just like how we ignore device files and suid/sgid files in
certain cases. Maybe this is something that ought to be one level up
from the ext2/3/4 filesystem driver?

In any case, this raises interesting questions. If we ignore permissions
on removable media, then anyone logged into your work computer (to which
you do not have root access) will be able to muck about with your files.
Is that something you want?
