It's pretty much decided: The server goes back to Arch Linux.
It's too much work and too risky to upgrade my OpenBSD. I have to wipe
the existing server and install a new image. But how do I know that
everything works as expected? I cannot test this, since I only have
*one* server. If things break, how do I roll back? I could export the
old image beforehand and then re-upload it. But this takes so much
time.
Or I could rent another new server and set up the new system there.
That would work, but it's expensive. :( And still a lot of work.
That's just not worth it. I never had to worry about these things when
using Arch Linux.
