In my opinion, based on the "stuff" needed for Epoch, Runit and s6, I'm
pretty sure you could have packages for each.

The tricky part is that /sbin/init will need to be one or the other.
Other than that, all three (and I assume sysvinit too) could coexist on
a disk, and which you use is simply copying, let's say, init.epoch to
init. My research during the Manjaro Experiments tells me that a mere
symlink from init.epoch to init fails: I don't know why.

Alternately, the init= in grub could be changed, but this is a
GARGANTUAN pain in the butt to do every time.
