Since my current high-end dev machine is being decommissioned, I'd like to request access to some devbox from Infra that I could use for my LLVM and PyPy work (build-testing new LLVM versions, and building PyPy binpackages). Both processes are CPU- and memory-intensive, so I can't really do them effectively on my own hardware. I don't know what kind of setup Infra uses now but I'd really use something containerized for different setups. Until now, I've been using a bunch of chroots on btrfs subvolumes -- amd64/x86 + openssl/openssl11/libressl + llvm-4/5/6/7... I've been using btrfs snapshot to clone existing systems to the new versions as I needed them. I would really prefer being able to create and maintain multiple systems easily and quickly rather than having to uninstall and reinstall dependencies all the time. I suppose one of the modern container solutions would be more effective at this than my old chroots but I don't really know anything about that, so I'd rely on your experience in choosing.
