Windows %PATH% shows as linux path, not windows path?
Description
I am wondering what is the source of this difference below?
I see a related discussion:
- https://github.com/containerd/nerdctl/discussions/2285
containerd --version
containerd github.com/containerd/containerd v1.7.5 fe457eb99ac0e27b3ce638175ef8e68a7d2bc373
nerdctl version
time="2023-09-09T13:18:19-07:00" level=warning msg="unable to determine buildctl version: exec: \"buildctl\": executable file not found in %PATH%"
time="2023-09-09T13:18:19-07:00" level=warning msg="unable to determine runc version: exec: \"runc\": executable file not found in %PATH%"
Client:
Version: v1.5.0
OS/Arch: windows/amd64
Git commit: b33a58f288bc42351404a016e694190b897cd252

GitCommit: fe457eb99ac0e27b3ce638175ef8e68a7d2bc373
runc:

Steps to reproduce the issue
nerdctl run --rm mcr.microsoft.com/powershell:lts-nanoserver-ltsc2022 cmd /c "echo %path%"
> /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
docker run --rm mcr.microsoft.com/powershell:lts-nanoserver-ltsc2022 cmd /c "echo %path%"
> C:\Windows\system32;C:\Windows;;C:\Program Files\PowerShell;

This bug is caused by a containerd bug here which only has default for unix env:
func WithDefaultPathEnv(_ context.Context, _ Client, _ *containers.Container, s *Spec) error {
s.Process.Env = replaceOrAppendEnvValues(s.Process.Env, defaultUnixEnv)
return nil
}
We are using the function here to set environment variables and end up overwriting the default windows path. I believe Windows Containers have a default path already configured at bootup so solution here might be to have WithDefaultPathEnv function do nothing for Windows?
Containerd issue resolved by this PR: https://github.com/containerd/containerd/pull/9118.

The fix for this was backported into Containerd 1.7.11 and 1.6.26. I've confirmed the bug no longer repros on the latest release of nerdctl
