the next steps are to productionize VM image construction (right now it's done semi-manually in an incredibly error prone process, should be done entirely in Nix) and integrate it into the overall IaC workflow

then Windows

basically any OS with a cloud-init disk image, a QEMU Agent port, and a Forgejo Runner port is easy to add, though some things are more easy than others and there are some nuances

(e.g. no official cloud-init OpenBSD images are available, so we'll have to build our own from scratch)

i think the benchmark is actually skewed against FBS runners because over ~half of the wall clock time is spent running tests with -j1 on a 8-core machine, but the same property probably probably makes it somewhat representative of real world conditions, haha

obviously a very unscientific comparison, i would not suggest this number is meaningful for anything but 'entertainment purposes'
