I've been learning Debian packaging and it isn't that bad, but it is a bit more involved than say an Arch PKGBUILD or whatever it you use on Crux. What exactly do you need to package? The repos are pretty huge, but if it's your own software I'll be happy to try and lend my assistance. If you do go with it, I wouldn't recommend using stable because while it is incredibly stable and good for servers, the games are too outdated so people can never connect to them. I use testing every day and it's still very stable, and despite the name unstable is still a lot more stable than Arch. On the other hand it's pretty boring, whereas Void Linux sounds fun.

Also I love Cube 2, if you get it running you best let me play ;)
