Description
Hello, I just wanted to test program compilation on musl libc with voidlinux-musl/alpine containers and checkout always fails with "unknown" while same command locally also in docker works fine like on this screenshot. Containers with glibc passes without any problems.

Here I'm leaving screenshot with errors and link to actions logs

Research direction
Start by reproducing the checkout failure with the reported voidlinux-musl or Alpine containers and the sh -c "cat /etc/*release | grep ^ID" command, then compare it with a glibc container. Use the linked Actions logs to trace where the result becomes unknown; done means checkout succeeds on musl-based containers without regressing glibc behavior.
