I know MX / Antix were Debian based and derived from Mepis/Antix and are systemd refusenix.
I did not realize they were rolling until I read this DW review dated 3/1/2019
I had MX 17.1
I have now MX 18 … Without realizing!
Just a few more updates!"
Or am I mistaken?
With ChromeOS, W10, Manjaro and … being rolling it is evident there is a good case for many fat-clients getting on well with rolling.
