Something like nixos-rebuild switch but only for "late-boot" services #3
Description
Currently nixos' activation script is a big mess (in my opinion); as it also restarts things that come before sysinit.target.
I think for most cases to activate a config people should just reboot, so that we never run into these issues.
However, I see the benefit for running services you install "immediately" so I would like to support
limited nixos-rebuild switch-like functionality but only for services that have DefaultDependencies=yes and are pulled in by multi-user.target
If the activation script detects any other things that need "restarting" it should refuse and advice a reboot
This eliminates obscure bugs; but keeps the interactivity of rebuild switch
