'expand' is really the root filesystem.  It's essential if you want to
automatically resize the filesystem *offline* (ie. without using
things like cloud-init).  However you can omit it from the format and
virt-builder just won't resize the root fs.

Actually it is:

  http://libguestfs.org/virt-builder.1.html#creating-and-signing-the-index-file

It just defaults to sha512 unless specified otherwise.

You can add extra fields, they will be ignored by virt-builder.
