Description of issue

I am trying to add cuda to a formula for Linux only, and I'm stuck on something.

First, when installing cuda via their .run file, I get the following output.

https://github.com/LizardByte/Sunshine/actions/runs/16401942638/job/46342656092#step:7:9023

  ./cuda_12.9.1_575.57.08_linux.run: 234: cannot create /dev/tty: No such device or address
  Signal caught, cleaning up

I believe cuda attempts to write output or errors here, but it's unable to access it from a homebrew environment. Is there anyway I can allow it to have access, or to re-route the output?

Second, this doesn't actually fail the build, instead it tries to continue and ends up failing later on. How can I make sure it fails when the cuda install fails?

I am working on this here: LizardByte/Sunshine#4097

I have attempted to search through the entire homebrew core repo for any hints about using cuda, for which I didn't find any. Any ideas how to get this working?
