Also what do other versions of the Linux kernel do on other more capable
filesystems if you set up ACLs in such a way that new files can be
created but their permissions can't be later changed (it may be possible
to set up the same scenario without ACLs by using combinations of setuid
and sticky bits on the destination directory)?
