I recently reformatted my personal machine from Slack 14.2 to Ubuntu, and did not have a fun time. The second time that Ubuntu randomly bricked my machine with an update, I changed tack. I'm now running Alpine Linux as my desktop, and I have to say it's absolutely a spiritual successor to Slack. Very similar installation process, very simple design, and I've had to re-learn how to set up a desktop, hardware, etc. It's been fun! It's extremely fast too. (and as a bonus: no systemd!)
