Oh, but it's even easier than that!!! You can use the "autoremove" feature!
If your system is booting properly on the most recent (read hightest number)
Linux kernel, you can automatically remove all the previous ones in one
command:
sudo apt-get autoremove
This will remove all the previous version of the kernel leaving you with
just the most recent version in your grub config. It will also clean out
any old cruft left behind if you've installed apps. For example, if you
installed the app foo and it had a dependance libfoo, the package manager
handled grabbing libfoo for you. Now, if you later uninstalled foo, libfoo
is probably sitting on your disk somewhere taking up space. Autoremove will
clean that out for you too!
Isn't FOSS wonderful!?!!?
Also, should you want the last entry selected when you last booted via Grub
to be selected as your default the next time you boot, this can be
accomplished easily with Grub2. Now, why you would want to boot anything
other than the most recent Linux kernel is beyond me, but I know one of our
fellow members "Dual Boots" some inferior OS and wanted this type of a
setup. Perhaps if we coverer Grub2 he would be willing to share his
experience in setting this up. What'd'ya'say Mr. D?
