Super
Jul 20, 2023
Allow others to run commands as root
Super is a setuid-root program that offers
o restricted setuid-root access to executables, adjustable
on a per-program and per-user basis;
o a relatively secure environment for scripts, so that well-written
scripts can be run as root or some other uid/gid, without
unduly compromising security.
The design philosophy behind super is two-fold
a some users can be trusted when executing certain commands;
b there are some commands, such as a script to mount CDROM's,
which you'd like to be safely executable even by users who
are NOT trusted. Although setuid-root scripts are insecure,
a good setuid-root wrapper around a sensible non-setuid script
can be hard to break, and super provides that wrapper so that
even a non-trusted user can use the scripts.
