Well, do you have any idea what software you're pulling (and under what licenses) if you run `apt install vim`?
Because let me tell you, if you think it's just vim, you're quite mistaken. And if you're distributing a docker image that contains vim, even for non-commercial purposes, it's technically your job to know. And perhaps to extend anyone downloading that docker image the offer of getting the source code for the specific version of any GPL software it might include, which it's up to you to archive.
Well it's vim, and any missing dependencies. If there license concerns up front I'll make sure I pick a distro/repo with compatible policy, like Debian main. If I want to double-check I'll run VRMS.
