I've cancelled my subscription yesterday, conveniently it was about to renew at the end of the week, so I have a few days to migrate from Proton, here's what I'm thinking of, but I'd love to hear what other people are switching to
i'd install k3s on the two boxes and just stand up a super simple container that doesn't need storage, think ntfy or something of the like, you can do that quick. getting shared storage up is a but more difficult :)
