Podman favoring Window Store version of WSL breaks podman for firewalled companies.

erw444 commented 2 months ago

Issue Description

Hello, It seems with Podman 5, there is a check to find WSL that defaults to the Windows Store version of WSL. Our company does not allow Windows Store applications as part of our security guidelines, so we have our users run with the built in version.

When we moved to Podman 5, this resulted in errors and having to delete the wsl symlink in APPData so that we could use the system built in version.

It would be nice if there was a config field to say which verison of wsl to use.

Steps to reproduce the issue

Install Podman 5 2.Start Podman
Error: fork/exec The process has no package identity

Describe the results you received

Recieved the following error when trying to start Podman. Error: fork/exec The process has no package identity

Describe the results you expected

Podman to start up successfully.

The code seems to check if the file exists before using it, https://github.com/containers/podman/blob/main/pkg/machine/wsl/wutil/wutil.go#L26

Is there a reason why this path would exists but cannot be used? Regardless looking at the git history this was added as some work around for a CI issue so I wonder if we could drop it and juts default to wsl from $PATH.
