If I make it a build-time dependency, isc-dhcp-client should end up in
the pacakges file. From there it will be added to the runtime
dependencies through the appliance:Depends variable (which is generated
using debian/gen-appliance-depends.sh).

Can we assume that the network name is always "eth0"? In that case, I'd
simply apply that patch.
