Version

redhat-actions/buildah-build@v2

Describe the bug

Running mkdir -p errors out on ubuntu-latest with:

error running container: error from crun creating container for [/bin/sh -c mkdir -p /mnt/rootfs]: cannot create state directory for `buildah-buildah504768355`

When buildah is previously used as root.

Here are the logs before the error occurs, if that helps:

Storage driver is not 'overlay', so not overriding storage configuration
Performing build from Containerfile

: exit status 1

Failing Action

Dockerfile

Steps to reproduce, workflow links, screenshots

1. Build/modify some images with buildah outside redhat-actions/buildah-build@v2 as root
2. Run a Dockerfile containing RUN mkdir in a GHA
3. Observe error

The action runs fine when buildah is not invoked in previous steps.

After switching from sudo to buildah unshare to run my script and only building with the buildah action, the issue has went away. It’s still weird how running a build as root would cause this, but it’s probably a non-issue.
