I somehow broke #nixos
@RaisinBread in which way?
and how did you achieve that?
was it easy to recover?
@RaisinBread sounds like an issue with stateful configuration (of kvm). if it would be possible to configure that with nixos, you would be able to roll-back. i had situations where xserver did not start with a new kernel and could just roll back and use lts kernel
maybe it would have been enough to stop kvm and start xserver again, and them remove broken kvm config
i guess you would have the same issue on any distro when doing the same thing (and have the same software version)
