I suspect the OP is referencing Void Linux[1] which makes use of runit as its init system. If not, it's the first thing that came to mind.

I'm not sure it's necessarily a better solution as it requires more manual interaction out of the box (namely creating symlinks by hand among other duties), but that might be argued as a feature. There appears to be a wrapper or two out there to automate away some of the tedium.
