I think the problem with btrfs is that it entered the spotlight way to early. With Wayland there was time to work on a lot of the kinks before everyone started seriously switching.
On btrfs a bunch of people switched blindly and then lost data. This caused many to have a bad impression of btrfs. These days it is significantly better but because there was so much fear there is less attention paid to it and it is less widely used.
@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
I suppose that’s a fair assessment. Thanks for the clarification!
However, I do give precedence over their current situations.
Regarding NixOS, it and other independent distros are absent in the link you provided. NixOS is literally its own thing and also old; older than Ubuntu and Android for example. So, if anything, it did deserve a mention. Though, I suppose the maker of that website didn’t think it was relevant enough to be included over three years ago. NixOS’ popularity has thankfully exploded in the mean time, though.
@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
