Hmm my first linux distro was Suse 5.x that came on 5 CDs (i think it was 1998) … can’t say I used it much, I had weird German ISDN Internet at the time and the PPPoverWhatever (forgot the exact name) just didn’t wanna work. Making music wasn’t really feasible at the time. It mostly lay dormant. I slowly climbed the learning curve and switched to Linux full-time in the mid-2000s, when a lot more things were possible …
I have to admit, when it comes to new developments in the Linux world, I tend to live under a rock … never switched to Wayland, not because I have any ideological reservations, but because my favorite WM (a minimalist WM developed by a friend of mine) is available only for Xorg.
I had heard about NixOS before, but until I stumbled upon this thread, I didn’t have a good understanding about what an atomic distro is. Now that I have a bit of an understanding, I guess I can only repeat what others said before, it seems to be solving a problem that I don’t have. I’ve been using rolling release distros for a very long time (at first Gentoo, like, 15 or more years ago, but Arch (btw) for over a decade now, with occasional, typically short stints in Debian-based distros), and the amount of problems caused by updates has been negligible for the last decade (Gentoo overlays 15 years ago could be a pain, for sure).
It does sometimes bother me that my OS config seems to so … static these days, but then again I have so many things going on in life on that I don’t feel a huge need to prioritize changing an OS that feels blazingly fast to use, stable, minimalist, and basically checks all the boxes. It just became my high-productivity comfort zone.
