The /boot bug is unreal, I just ran into that a few months ago.

It's super frustrating. There's no reason I need twenty kernels on my machine :-p

Ubuntu actually only keeps the current and the previous kernel as necessary and give the user the option to purge all the old kernels. These old kernels will be marked as autoremovable and by setting a flag in unattended upgrades config you can make it autoremove those. On desktops this happens automatically.

On RHEL, it happens on servers, too - anything is better than your /boot partition filling up on its own!

It shouldn't, the default is to keep 6 recent kernel packages.
