control

control(8)

control is a framework allowing to select one of several fixed configurations for tasks lending themselves to such a selection; it is used in ALT Linux and Owl GNU/*/Linux to manage SUID/SGID binaries in the first place.

Thus control cdrecord public and control cdrecord restricted commands will allow cdrecord use to all users or to cdwriter group members only, appropriately.

One can list all the facilities available along with their current state and allowed states by running control with no arguments.

control runs a corresponding /etc/control.d/facilities/ script to switch state. Implementation of particular facility switcher is up to its developer's fancy :)

E.g., cdrecord script changes permissions for cdrecord binary while cups script edits cupsd.conf regarding RunAsUser.
