Basically, yeah. I have no need for patching without downtime (not really in the scope of lux anyway), I just don't like how the upgrade method tends to be either keeping track of development through patches or starting over from a clean config or other methods. I greatly enjoy the automated approach binary distributions have.
I guess if you really, really had a use case for it, binary patching using one of the open-source solutions might be feasible. Otherwise, HA load-balancing FTW.
I'd never heard of Exherbo; thanks for the pointer. (I've been looking at Nix and Aboriginal in search of a minimal distro that I can figure out how to put into a single repo and build with a single command.)
