You could just look at my profile to see that I’m not. I’m also not new to Linux communities in general. Doesn’t change that I’ve never seen someone recommend NixOS to a complete beginner. I have (rarely) seen Arch recommended, but those recommendations will generally be downvoted and have many replies disagreeing. Linux Mint is by far the distro I see most often recommended, followed by Fedora.

I’ve genuinely never seen a single person recommend NixOS to a new user, unless they already had advanced technical knowledge

Its not hard to copy your aliases to other machines. All my machines run NixOS, so they all have my home manager config. I would assume you could easily copy shell configs with tools like ansible as well. For aliases it’s as simple as copying your .bashrc over.

At my last job where I was regularly doing this, every user had a home directory that would be mounted onto any server we accessed, so all of us could have whatever shell customizations we’d like.
