It looks like it’s for their immediate family. I had issues with this when I was supporting people I didn’t live with, but if they’re using the same PC, it shouldn’t be an issue until something breaks.

I use NixOS, Gentoo, and Debian:

• NixOS because I like declarative configuration files.
• Gentoo because I enjoy compiling from source.
• Debian because the other two are more difficult to use.
