Hmmm... /boot is too small. what's the best way to increase it's size?
I recently did a "apt update ; apt upgrade" and it died for lack of space in /boot when trying to install the latest kernel.
I purged a couple of old kernel packages (still present in the 'stable' repo, so they weren't obsolete) to make enough space and tried again. Worked this time, but I would have liked to have the old kernels around as fallbacks just in case of a regression...
Here's the disk layout:
rbthomas@milli:~$ lsblk

What's the best way to increase the size of /boot ?
I can easily create a gig or so of space by a shrink/resize of /home, but how do I add that space to /dev/sda2 ?
I can't just move up the end of /dev/sda2 = start of /dev/sda3 without backing up and restoring, can I?
Any suggestions would be appreciated.
Rick
