Title:
   apt-get autoremove takes forever

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  While trying to clear out old kernels in a UEFI system (8 or 9 surplus
  generations), I noticed that the apt-get autoremove command issues an
  update-grub command internally and rebuilds after >>EVERY<< generation
  deletion. This results in multiple rebuilds of the Grub
  configurations, including even those older generations that are
  subsequently going to be removed in a later pass.

  While appreciating that there is a necessity for fallback at all
  times, is there not a more elegant and time saving way of doing this,
  maybe adding a parameter as eg. "apt-get autoremove min_generations=x"
  where there is specified parameter for minimum number of old kernels
  are kept (suggested minimum default current +2 back levels) and the
  rest deleted? This could enable a one pass autoremove, useful when new
  kernel versions are coming out every 5 minutes.

  Grub2 version 2.02~beta2-36
