Alpine.

Have used crux but using low end / old hardware results in almost permanent building software.

I wonder how far we are from CI drivers ala Nix that fork builds out to idle hardware like a distributed torrent network. As someone with three out of tree modules in use, there must be dozens of us I’d like to think.
That is something I’ve already run into at my previous workplace. The name escapes me atm…
