Which commit of rust-lang/rust did you port it from? I'm seeing a bunch of differences with rust-lang/rust@d29e478.

[pantha704]

It isn't a direct port,
I wrote a simplified version based on the original's
approach.

Removed the isX86()/isGitHubRunner() conditionals since this repo
only runs on GitHub Actions.

The core cleanup logic (packages, docker, swap, directories) is the same.
If you'd prefer a closer match I can update it.

[bjorn3]

A closer match would be preferred. And if you don't mind, please also link the exact commit you ported it from.

[pantha704]

I've updated the script to be an exact port of rust-lang/rust including all the conditionals and helpers, as requested.

The source is src/ci/scripts/free-disk-space-linux.sh from commit d29e478.

I verified the content matches closely

Thanks!
