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.

Sounds good in theory.
But I've had so many issues with D-Bus fucking shit up on my systems that I'd be very reluctant to hinge my only way of recovering from failures upon something so brittle.
Granted, D-Bus hasn't given me any trouble since moving to NixOS. The hell of trying to recover my arch systems from a perpetually failing D-Bus would make me very apprehensive to adopt this. I could see myself using run0 by default, but keeping sudo-rs or doas around with a much stricter configuration as a failsafe until the run0 + D-Bus + PolKit is absolutely stable and bulletproof.
I haven't had D-Bus problems in quite a while but actually run0 should help with some of those issues. Like,
systemctl --userwill actually work when used with run0, or at least systemd-run can.Haven't used it yet so it's all theoretical, but it makes sense to me especially at work. I've used systemd-run to run processes in very precise contexts, it's worth using even if just to smush together schedtool, numactl, nice, taskset and sudo in one command and one syntax. Anything a systemd unit can do, systemd-run and run0 can do as well.
I'm definitely going to keep
suaround just in case because I will break it the same I've broken sudo a few times, but I might give it a shot and see if it's any good just for funsies.Just trying to explain what it does and what it can do as accurately as possible, because out of context "systemd adds sudo clone" people immediately jump to conclusions. It might not be the best idea in the end but it's also worth exploring.
At that point just set a break-glass root password and don’t use sudo or doas.
