not sure who started it => Outcome of one of the Berlin meetups ==> tomes of machines, where the hardware config was in multiple repos, It was expected that things are breaking with different nixos versions
Not easy to keep in sync with nixos channels
remove/add for different channels to make it work
Ideally, hardware-specific modules should only contain configuration that cannot be autodetected, e.g. no "enable Intel microcode" config. So quirks etc.
