Hi Guido,

I didn't mean to accuse Debian of doing a bad job with netcf.

It is just that I have configuring my networks in special ways for
nearly two decades, using the "manual" method of ifupdown way before it
was officially introduced into the Debian packages (#88948, sic!), and
am therefore used to other packages doing network configuration not
playing around pretty well on my systems.

And I have stopped using ifupdown entirely with jessie, and have
migrated over to systemd-networkd. My expertise with current ifupdown is
to limited to be of any use.

I would love to see systemd-networkd support for netcf, though.
