This is how the Debian package of libguestfs works (Hilko's official
package, not my one).

However this is troublesome because it means any security problem in a
dependent program is baked into the appliance.  Applying a security
update to the host wouldn't update this libguestfs appliance.  Compare
this to the way febootstrap-supermin-helper normally works (eg
upstream, Fedora and RHEL): the appliance is rebuilt whenever any
change is noticed in a dependent program.
