Created attachment 216739 [details] Change default compressed filename to "${_uuid}.zfs.xz" The default filename for compressed images is "${_uuid}.zfs.z" withe the default decompression command as 'xz -d'. xz(1) will refuse to decompress a filename with an unknown extension. Changing the default filename to "${_uuid}.zfs.xz" should take care of this.
