Add support for ZFS

[Zesko]

Is that possible to support ZFS filesystem via GUI or CLI?
See the example:

Thanks!

I think it can be implemented on GUI, with some considerations. Encryption being the main one. I think native zfs encryption is not supported still. Encryption will be via LUKS. I'll work the basic implementation first :)
