Get the Kernel sources for actuated to build with kmod or DKMS etc

Usage:

- uses: self-actuated/get-kernel-sources@master

The version will be determined via uname -r, i.e. 5.10.201.

In this instance, the sources would be be downloaded to /usr/src/linux-headers-5.10.201 with a source and build folder being generated.

You can then proceed with a DKMS or kmod build of whatever you require such as eBPF, Wireguard, or ZFS.

Caching with actions/cache is likely to improve the speed of getting the Kernel sources, rather than fetching them directly from git.

For example:

Cache Size: ~434 MB (454865493 B)
Cache saved successfully
Cache saved with key: Linux-aarch64-6.1.90

Caching is enabled by default; to disable it, you just need to pass cache: 'false' input, eg:

- uses: self-actuated/get-kernel-sources@master
  with:
    cache: 'false'
