There is a new pull request by abenson against master on the void-packages repository

https://github.com/abenson/void-packages kernel_bootsize_hook
https://github.com/void-linux/void-packages/pull/44137

[RFC] base-files: add kernel hook for /boot freespace
    <leah2> we should make a kernel install hook check that prints a big
            warning if /boot is full after running it...

Thoughts:

1. Change the threshold size? Make it configurable?
2. Change the threshold to a percentage? I think that's less useful.
3. Change what package this is shipped with? I'm not sure if it applies to all configurations we support/consider.
4. Wording of the message?

A patch file from https://github.com/void-linux/void-packages/pull/44137.patch is attached
