# The interface version prevents NixOS from switching to an
# incompatible Upstart at runtime. (Switching across reboots is
# fine, of course.) It should be increased whenever Upstart changes
# in a backwards-incompatible way. If the interface version of two
# Upstart builds is the same, then we can switch between them at
# runtime; otherwise we can't and we need to reboot.
