Why ? I guess you do not get this unless you have systemd, that is fine by me. If I would use anything outside of sudo I would go to doas.
My home distro does not have systemd, so I guess I may never see run0.
I have been evaluating the various BSDs for a few years in case my distro is forced to use systemd and friends. The distro I use is fighting the good fight against large monolithic tools, but it is having a hard time trying to avoid these monolithic tools.
With Linux slowly forcing systemd, Wayland, various Desktop Environments and now this, my move to a BSD may happen sooner that later.
Curious, I wonder how close run0 is to how Windows raise auths ? With LP now working for Microsoft, is he cloning tools from Windows for use in Linux ?
