autoremove should always leave you with exactly three kernels, the one
used at original install time, since this one is known to have worked
back wen you installed the system (this can be a really old one in case
of LTSes that have been installed from the .0 release), the last one
you upgraded from last and the new current one...

indeed, if you want to drop the original one or the last known good
one, you can manually remove either of them, but the next autoremove
will still leave you with three kernels by default so this is a bit of
a sisyphus job if you want to do it every time though ... :)
