Public bug reported:
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.
