@cmainas Can you guide me why these two test cases are getting failed?

@cmainas Can you guide me why these two test cases are getting failed?

These are both linting errors, because of spelling. I think updating https://github.com/urunc-dev/urunc/blob/main/.github/linters/urunc-dict.txt should be enough.

⧗   input: feat(config): pass rlimits to urunit via UCS

This extracts the rlimits from the OCI spec in the unikontainer
logic and appends them to the UCS configuration block generated
in linux.go. This allows the guest init process (urunit) to
enforce resource limits.

Fixes #253

Hello @codesmith25103 , in order for these changes to be effective, we also need to update urunit to parse the updated config and apply the rlimits to the process. Therefore, we can not merge this without urunit supporting them. If you want you can also try to implement the necessary changes in urunit too. Otherwise, I will work on it when I find time to do so.

[codesmith25103]

@cmainas I will try to update urunit and will update this PR.
Thank You
