Does it work when you remove the :z?

Does it work when you remove the :z?

Yes it does. What is this z ?

[Luap99]

z stand for selinux relabeling which requires extended attributes. I am not sure if virtiofs support this.

If it works without out it you do not need it.

[rhatdan]

Mac file systems based on Plan 9 does not support SELinux labeling z and Z should not be used. When we transition to use virtiofsd, it should support SELinux labeling, and then we can use it for better container separation on the MAC.

Currently the volumes mounted into the VM are labeled as nfs_t, and all containers are allowed to read/write the content.

Hey

I am currently trying to support macOS and linux (fedora) machines using the same play kube file. Is there a recommended approach here? Or is the answer "not cross platform yet"

[rhatdan]

Please open a new issue. Do not add to a closed issue. Podman play kube should work on a MacOS

To save people from struggling,
use docker.
