Is it possible to ristrict filesystems to certain users and processes? For example, could I mount /proc, /var and /tmp so that only root can r/w to those filesystem? Also, how could I implement the same thing but to the /etc directory and subdirectories? I am running Debian 2.2 with Kernel 2.4.5. All of my partitions are Reseirfs except for the /boot partition which remains ext2. My /usr partition is mounted as ro. Stef
