I had tried this approach, to add /etc/dhcp/dhclient-enter-hooks.d/resolved 
to excludefiles, however it didn't work.
As far as I know, this hook is included in the base image and according
to [1], the current implementation does not apply excludefiles to the base
image.

Why not add it as excludefile when building the supermin appliance,
instead?  This way, Ubuntu would not even need to do any changes in
libguestfs itself, and that excludefile can be shipped by the same
package installing that dhclient hook.
