Contrary to networkd, netctl is profile based. This makes netctl
useful in changing environments.
If networkd exposes its dhcp client, this patch makes it easy to add
support for it to netctl.
Even better, if networkd exposes a lot of its functionality, netctl
could potentially drop the dependency on iproute2 (not that there is a
problem with iproute2).
There are other dhcp clients (such as udhcp) for which support can
already be implemented easily after this patch is applied.
