easimon/maximize-build-space

easimon/maximize-build-space: Github action to maximize the available disk space on Github runners

This action optionally uses the sudo rm -rf /usr/share/dotnet trick that I used to free up more disk space, but easimon/maximize-build-space go far beyond that, with great documentation about how everything works, e.g. a 4GB swap file on a temporary disk that has 10GB free, etc. Quite fascinating.
