Hi all, I'm trying to set up a mounted filesystem that is read-write for root, but read-only for anyone else. It will be mounted as a backup directory, so files listed in that directory will be owned by current users on the system but can't be writeable, regardless of the file permissions. Example <normal filesystems mounted from hd1> hd2 mounted rw in /root/backup-rw hd2 mounted ro in /backups Only root should be able to write to anything under /root/backup-rw/ even though normal users will own files in that directory. Normal users should be able to read anything that permissions allow in /backups so that they can restore files from the backup. I was planning on using the nullfs fs type to achieve the second mountpoint for the fs. Is this possible? Thanks, Andrew
