On some systems (SystemV-ish), the euid/egid are used by default, and I think the sgid bit can be set on the directory to change that to the BSD style. The BSD behaviour is the only one that POSIX requires. I believe that ACLs can be used to get the type of permissions you want, but I don't know the syntax offhand. > The basis of the reason for my interest is that I'm trying to use > NAS4Free, and when I create a volume and export it out NFS, every file > is getting the wheel group there too.

Normally, for directories where anyone can create their own files or directories, we use the sticky bit. /tmp is set up this way, for example. And normally every account has a home directory, owned by them and their personal group. _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
