Uses dd to dump zeroes into a raw .img of the preconfigured size.
Goes further and rsyncs strapdir into the image, installs bootloader and a
kernel.

## img_partition_dos() ##
Partitions the raw image into dos format and formats (boot=ext2; root=ext4)

## img_partition_gpt() ##
Partitions the raw image into gpt format and formats (boot=ext2; root=ext4)

## img_rsync_strapdir() ##
rsyncs the strapdir to te mounted rootfs of our raw image.

## img_install_bootloader() ##
calls functions from sysconf: `conf_install_kernel` and `conf_install_grub` to
install the on the image

## img_mount() ##
Mounts the root and boot partitions in `$workdir/rootp` in order to work on it.

arguments, user and command in the style of:
