[ale] static ip network configuration

[Russell L. Carter]

Hi Steve,

Oh that is cool, if I understand it right.  On
debian, I *think* the ancienne style /etc/network/interfaces must be
pre-empting whatever systemd uh... network startup stuff would do.

So if interfaces(is, what, empty?) is not enabled wouldn't that
mean systemd just starts its galactic network configuration system?
I mean, if I can a install debian base and then drop your script
wherever and it works even with systemd, I'm going to reconfigure
my machines pretty soon.  Ah I just realized this could be
done by ssh at system install time.

I hate to spend time testing this stuff right now as I've got open
latex and lisp projects sprawled around.  *grumbles* if I only knew
how to work a Mac... ;-)

I tried a bunch of different window frameworks a few years ago and
decided that rather than fight the network idiom and menu forests
I'd stay with my slowly evolving over a quarter century now FVWM3
configuration along with /etc/network/interfaces.  The CLI is
going to be part of my neuron preservation strategy as I age into
ah my golden years.

Cheers,
Russell
