This is the only instance where libvirt knows about libguestfs.  All
other steps are libguest only or involve libguestfs knowing about
libvirt.

Would it be possible introduce a "domain-builder" concept into
libvirt?  When libguestfs is installed it drops a domain-builder
configuration/script that libvirt can pick up.  Then you can say
something like virDomainBuild(name="guestfs-appliance",
builder="guestfs").

Does febootstrap-supermin-helper need to be dynamic or could
libguestfs create a /var/lib/guestfs/appliance-initramfs.gz on
install?  Then libguestfs on the client can create the appliance
domain and point at that static initramfs file path.
