Have you looked at ACLs?

getfacl
setfacl etc?

They do provide more fine grained controls. Eg: file owned
by root:root,
but you want user "popeye" to be able to write
to it.

eg: setfacl -m u:popeye:rwx,u:oliveoil:r filename


rememeber to mount your dir with "acl" mount -o
remount,acl /dev/hdX

Thanks I'll look into that but it seams more user/access
orientated
rather than giving me more elaborate permissions/attributes.
I seem to remember that in Novelle DOS 7 199* they had
security
attribs/perms like create,delete,overwrite,move,read so that
if you had
only overwrite and read you would be able to edit a file but
not delete
it.

Some thing like that around? Inoticed that vserver seems to
use some
sort of attribs but can't quite figure out how they work
exactly

what about chattr?

chattr -i file would make it immutable.
-a would make it in append mode only.

would that work?
