That means that mklive just needs xbps to generate working images.
Usage: mklive.sh [options]
Options:
-r <repo-url> Use this XBPS repository (may be specified multiple times).
-c <cachedir> Use this XBPS cache directory (/var/cache/xbps if unset).
-k <keymap> Default keymap to use (us if unset)
-l <locale> Default locale to use (en_US.UTF-8 if unset).
-i <gzip|bzip2|xz> Compression type for the initramfs image (gzip if unset).
-s <gzip|bzip2|xz> Compression type for the squashfs image (xz if unset)
-o <file> Output file name for the ISO image (auto if unset).
-p "pkg pkgN ..." Install additional packages into the ISO image.
The mklive.sh script generates a live image of the Void Linux distribution.
This ISO image can be written to a CD/DVD-ROM or any USB stick.
