From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The thing with this is: its just a symlink to the systemd-run binary, which talks to PID1 to spawn new processes (in separate cgroups IIRC). Its one of the most fundamental parts of systemd. Even the debian systemd package includes systemd-run.

I guess the other question is if some tools the distro provides might switch to supporting it by default. For example on Arch there is makepkg that should never be executed as root, but does internally call some things with elevated privileges (mostly pacman to install and remove packages). Currently it checks for sudo and if not falls back to su, but maybe it might be worth considering changing su for run0 if its guaranteed to be there.
