Actually, I have a reminiscence of immutable flag only begin allowed to
be changed in the single-user mode. I cannot find a trace of this in the
current kernel code. May be this was from the pre-capabilities,
securebits driven security framework.
Anyway, this looks like user-mode solvable problem: just teach
/sbin/init to drop CAP_LINUX_IMMUTABLE on leaving single-user.

So, take it.
Patch is against 2.4.5. All attributes are inherited from the parent
directory. Only "immutable" and "noatime" actually work. "nodump"
attribute changed to mean "notail": suppress storing of the last portion
of a file in the tree itself.
