Writable /private/tmp

[ShamrockLee]

Expected Result
I expect /private/tmp to be writable, as many programs assume so.

This might be dumb and duplicated, but I did search across the documentation and issue using different keyword combinations.

Actual Result

Darling [/Volumes/SystemRoot/home/shamrock/Projects/ShamrockLee/playground/test-nix-in-darling]$ stat /private/tmp/
