This is the first edition (I think) of antiX with an alternative to sysvinit. This is runit, the same init/service supervisor Void and Artix use. As far as I know this is the first application in a debian based system.
Check https://antixlinux.com/download/ for a close mirror to test run a live image. The X is configured with ICEWM and antiX’s huge assortment of tools and helpers. For information on how runit works I recommend https://wiki.voidlinux.org/runit and https://wiki.artixlinux.org/Main/Runit (void and artix linux wiki pages), although antiX’s implementation of runit seems a little different.
Very good work and very refreshing to see something like this on a debian based system.
