My non-expert opinion:

1. ideally there should be an indication in what circumstances
    the above is required, because it might not be possible to infer
    for the non-expert (with regards to the above) user  
     
2. if it needs to happen, where in the buildworld/kernel/install/
    etcupdate/reboot sequence is it required? I would guess after
    etcupdate and before reboot, but guessing isn't the same as knowing.
    It would be great if this was in the Source of Truth(tm).

thanks,
