I'm looking to run rootless containers stored on a ZFS volume and I'm wondering if it's possible yet to use the native overlay storage driver (i.e. not needing fuse-overlayfs) in that configuration? I get an error with Podman 4.3.1 on a Debian 12 system:
Error: 'overlay' is not supported over zfs, a mount_program is required: backing file system is unsupported for this graph driverNative overlay for rootless has been possible since kernel 5.13, and OpenZFS got general support for overlayfs in 2.2.0, so it seems the compatibility is all in place. Is this perhaps an arbitrary restriction of the older Podman in Debian stable?
