<disk type="gpt" name="sda">
  <part size="50%" name="/" format="8303" />
  <part size="40%" name="/home" format="8302" />

- use sgdisk? scripting (generated by python) for disk partitioning (part types listed at http://www.rodsbooks.com/gdisk/walkthrough.html )
-- actually, might want to use parted --script instead? then we can do percentages. https://www.gnu.org/software/parted/manual/parted.html

- add mkfs-ing

-support serverside "autoconfig"- a mechanism to let servers automatically generate xml build configs. e.g.:
  kernel ... aif_url="https://build.domain.tld/aif-ng.php" auto=yes
would yield the *client* sending info via URL params, e.g.
  https://build.domain.tld/aif-ng.php?disk[]=sda&disk[]=sdb&disk[sda]=300GB&disk[sdb]=500GB
? something like that.
