Introducing run0: Run Processes as Other Users with systemd
Lennart Pottering, the well-known developer and creator of systemd, has recently introduced run0, a new utility that allows users to run processes under the identifiers of other users. Positioned as a more secure replacement for the popular sudo program, run0 is implemented as an add-on to the systemd-run command and is included in the release candidate release of systemd 256.
