Honestly, the times aren’t too bad as long as you have a recent CPU! It definitely varies though - on my main PC, compiling glibc takes about 15 minutes, on my netbook that I had a smgl install on, it took about 20 hours lol
SourceMage! It’s a source based distro like Gentoo. I’ve been using it as my main distro for a solid 10 months now, I’m very happy with it! We have flatpak so steam works great, as well as lutris and everything else. Definitely wouldn’t recommend it to someone looking for simplicity though!
