Incus already supports exposing ZFS to the container on systems running ZFS 2.2.
There’s is a zfs.delegate storage volume option to control it.
Worth noting that Incus 0.x is just as stable, supported and released on a similar cadence to LXD 5.x.
We just want all Linux Containers projects to have aligned version numbers so Incus will jump straight to 6.0 at the same time we release LXC and LXCFS 6.0.
