Rustaceans at the border

I've run Gentoo on 10s of systems for well over over a decade. There are plenty of other, far more straightforward, ways to break a Gentoo box! For starters, emerge will pull down the dependencies and build them first and work up the chain to the final result. Unless you go mad with eclean, you'll have all the bits on site.

I do understand where you are coming from though. It all sounds a bit ... devops. Before you know it we'll be piping curled configs through configure/make.
