Are you using Linux at work without systemd? Seems unlikely. All our 400+ nodes run RHEL and consequently systemd. This doesn’t seem to impact our researchers’ use of CUDA in the slightest when executing code on the nodes or in any kind of container.
With other init systems you don’t have to write any custom config files. You just have to start docker; it already has container maintenance built-in.
I’ll never understand why they had to complicate it and require every container to also have a unit of explicit management.
