Usage: $PROGNAME [options] <rootfs-tarball>
The <rootfs-tarball> argument expects a tarball generated by void-mkrootfs.
The platform is guessed automatically by its name.
Accepted sizes suffixes: K, M, G, T, E.
OPTIONS
-b <fstype> Set /boot filesystem type (defaults to FAT)
-B <bsize> Set /boot filesystem size (defaults to 64MB)
-r <fstype> Set / filesystem type (defaults to EXT4)
-s <totalsize> Set total image size (defaults to 2GB)
-o <output> Set image filename (guessed automatically)
-h Show this help
-V Show version
Resulting image will have 2 partitions, /boot and /.
