I should figure out how to safely move an interconnected setup of multiple docker containers from one host to another while temporarily storing it in some form of offline image.
Background: I have one vserver left on Gentoo linux (don't ask it was the best choice back then) and things like updating the system profile, which is sometimes required as part of security mitigations, takes atrociously long. I just updated GCC and it took a bone crushing 5 hours.
