Hi

I would like to make a patch for this if somebody is willing to mentor me.

The idea is

  * removing symlinks-procedure
  * argument to remove x old generations.
      o ex guix system remove-generation --keep-2
        this would remove all system generations besides the latest 2.
  * warning if user tries to remove so that less than 2 genererations
    resides
  * hinting to run guix gc
