I’ve been having trouble finding vi/vim lately on some installs, namely Ubuntu, although maybe they just leave it out of the default docker image? I use it sometimes for debugging conf files in between docker builds. But if you have to install something anyway, maybe it doesn’t make any difference if it’s vim or nano (emacs, though, I mean come on).

I think also I was on a real Linux box a few weeks ago (can’t remember what distro, sorry) that only came with ed by default. That was interesting, at least until I gave up and installed vi.
