the disk image and mount it to \$WRKDIR/world before
installing the contents to the image
-c overlaydir -- The content of the overlay directory will be copied into
the image
-f packagelist -- List of packages to install
-h hostname -- The image hostname
-i originimage -- Origin image name
-m overlaydir -- Build a miniroot image as well (for tar type images), and
overlay this directory into the miniroot image
-n imagename -- The name of the generated image
-o outputdir -- Image destination directory
-p portstree -- Ports tree
-P pkgbase -- List of pkgbase packages to install
-s size -- Set the image size
