That sounds *alot* like the stuff rpm can do without bloating the kernel.
Perhaps an intelgent thing to do would be to have the FS support 'extended
metadata'. There could be a pointer at the end of the metadata block to
some 'extmetadata' node someplace. At the node there could be n where
n<256 key=value pairs. This could be used to store ACLs, compression info,
and such. (pref things that arn't needed every file access) There could
also be some syscalls so that userspace apps could add/remove/view these
things..
Sounds neat, but how would it perform?
