The loopback device is set up very very early at boot in
src/core/loopback-setup.c in C code. In virtually all cases that should
be entirely sufficient to get the loopback interface set up, and you
don't need anything else.

DHCP does not apply to the loopback device as the loopback is
unconditionally configured to, and dynamic configuration is
not necessary.
