Hi,
Linux gives you part of the functionality you want via the 'setgid' flag on
the directory:
"[...] a file's permissions have three special components, which affect
only
executable files (programs) and, on some systems, directories:
1. set the process's effective user ID to that of the file upon
execution (called the "setuid bit"). No effect on directories.
2. set the process's effective group ID to that of the file upon
execution (called the "setgid bit"). For directories on some
systems, put files created in the directory into the same group as
the directory, no matter what group the user who creates them is
in.
3. save the program's text image on the swap device so it will load
more quickly when run (called the "sticky bit"). For directories
on some systems, prevent users from removing or renaming a file in
a directory unless they own the file or the directory; this is
called the "restriction deletion flag" for the directory."
A quick check verifies that Linux (2.4.13 at least) implements the semantics
in '2' above.

Subject: [expert] Forcing UID/GID for certain directories/trees?
Hello,
I have a certain directory tree that I'd like to ensure always has the
same owner/group for the contents therein, regardless of who created or
last modified those contents (let's disregard the security implications
for this discussion). Something similar to how umask works for
permissions, only for GID/UID. I can obviously have a script running
that resets the permissions every n number of seconds, but this is a
horrible kludge, and I'd like to have something a bit more graceful.
Also, I'm having difficulty figuring out how to have different umask for
different areas of the filesystem. Is this possible in Linux?
Thanks for any and all replies.
