@lancalot the “main” that are alive today are (like on this graph) https://rreinold.github.io/explore-linux/ :Debian, Slackware, RHEL, Gentoo, Arch & android
These are only the alive ones, however, I couldn’t find any info about Nix OS so it remains on the maybe category cause I tried it and could not find any hint to the past
@lancalot I understand the list I provided is not necessarily complete, because Void & Solus are also independent, however, for them to be “main”, they should have “derivatives”, I don’t claim that I have a big Linux experience, but I tried & documented myself about the distros on the list, & can confirm that they are “main”, I also tried Nix OS, the use of 1 config file is refreshing, however that ease comes at the cost of some flexibility, installing Steam there is too complicated for me
