@notverypunny not many 2 and a recovery.
But I have seen many more on past systems so I wanted to take a look into it. To see if this is/was something most people are managing manually.
Do you have an Ubuntu system that has been around a while? Look at one of those and you'll see one reason why me and @JaredBusch actively hate Ubuntu.
No I don't have any remaining systems of importance that I've seen this on. Just from recollection did this come to mind.

I've got XOCE in my lab, but that's not critical to my day to day.

@DustinB3403 You never touch grub yourself. You let the system take care of it for you when it adds or removes kernels.
As to removing old kernels, it depends on the distribution you use. A good distro just takes care of this for you. The annoying ones make you do it manually.
RedHat/CentOS/Fedora = automatically cleans up older kernels. You don't do anything and it will keep a sane number by default. I think it's 4 and a recovery option.
Debian/Ubuntu = keeps all kernels till you manually remove them. I forget offhand what the command is besides it's an option for apt.
This is one reason I'm happily moving things from the old rental box to my new server for my home lab. The old rental box has Ubuntu with a tiny little 256MB /boot partition. It can keep ~3 kernels, and that's it, ugh!
For Debian/Ubuntu it is
sudo apt-get autoremove --purgeBut that should happen when you do update as you don't want an old lingering kernel to cause trouble...

Should happen, and does happen, are two different things in Ubuntu.

https://help.ubuntu.com/community/RemoveOldKernelsIt only works if we set up unattended upgrade to remove old kernels.

Correct

OMG, so this.. If using unattended upgrades, make sure autoremove is configured properly.
I had a box take a dump because it ran out of space in /boot with a ridiculous number of old kernels installed.
Trying to run autoremove failed because it requires some space to do its work.Had to manually remove a bunch of files before autoremove could run...

You can install without /boot. IIRC there is a other config change with unattended-upgrades to auto remove kernels.

You normally can, yes. Since my current home lab box is a rental, I could only choose from the options they gave me at the time. Today, they'd let you use your own iso, but still wouldn't recommend them for anything other than a test lab.
