Description
Podman run fails with Error: error chowning container 01041b61625c64e34a849b974c5aa9dcc34377fd5025b9ee7fd629b2a0c5ad79 workdir to container root: chown /run/user/1000/test: read-only file system when I try to run a container with a read only rootfs.
This worked with v2.2.1.
Steps to reproduce the issue:
$ ROOTFS=/run/user/1000/test
$ mkdir $ROOTFS
$ podman unshare mount --rbind -r / $ROOTFS
$ podman unshare mount -t tmpfs none $ROOTFS/run
$ podman run -i -t --rootfs $ROOTFS sleep 5
