I really wish there was a system wide package manager for docker containers, which would update software in all your containers at once similar to how a typical package manager would.
I did not completely rule out docker, but I wonder if I can obtain most of its benefits without this major con with package management. I mean I know it’s possible, since its mostly kernel features, but it would be difficult to simulate and the tooling is probably lacking (maybe nsjail can get me closer).
