CHKBOOT ALERT! on /boot/ disk out of space

[jhanger-dev]

System:

Dell Precision 5550 / BIOS 1.7.1 03/29/2021
Ubuntu 20.04 LTS
chkboot 1.3-5 - dpkg

Issue Description:

I recently encountered console alerts[1];
Turns out I hadn't cleaned up my deprecated kernel packages.
As a result my /boot/ partition ran out of space.
This caused chkboot and chkboot-check to not be able to update the hash files.
This resulted in the Alert in [1] and running chkboot did not alert to there being an inability to write to the files so It wasn't until a few days of getting the nagging alert every time I opened a new terminal or logged in from a terminal that I figured out the issue.

There should be some sort of alarm going as when it writes to the disk certainly there are errors generated from the OS level that appear to be ignored.
Perhaps here is the appropriate location:

chkboot/chkboot

Line 77 in 33ea875

done > $BOOTFILES

Or maybe a new code block above that checks for disk space prior to writing hashes.

This isn't some show stopper just more of a nuisance that can be more readily fixed on the occurance as from time to time after many updates i've seen /boot run out of space.

Thanks for reviewing this issue.
