Note that it should be relatively straight-forward to implement a
generator (even in shell...) that generates native systemd-networkd
configuration snippets from ifcfg files at runtime (or upgrade-time),
similar to how we convert fstab or crypttab to systemd units. With that
in place it a smooth transition from the old networking scripts to
networkd should be possible.

That said, there are some things ifcfg supports (ISDN, IPX, ...) that
we'll never support in networkd, hence we couldn't claim 100% compat
with such a scheme.

Note that networkd supports static configuration, bridges and some forms
of tunnels just fine.
