2021-05-17 autoupdate: v1.6 released

A new version of the autoupdate tool. The ability to remove old kernels is now available and automatically performed any time packages are updated.

The newest three kernels are always kept on the system for troubleshooting purposes. Anything older is automatically removed as long as it’s not currently running.

autoupdate now also creates the file /var/run/reboot-required when a new kernel is installed. This can be used to auto-reboot a system if desired.
