Yes I could, this is what I mean by generate the file.  I am trying to
avoid that.
If I have to swap out a machine, then I get a new mac, and I have to
update the file.
And this pattern comes up fairly often: I want a machine to have a
defined IP, and I would like the dhcp server to be the source of truth
defining what machines get what IPs.

I generally maintain a list of mac/IP/hostname, likely in a
spreadsheet.  or maybe a text file checked into version control.  If
dnsmasq could read this file, it would save steps and less chance of
my file and the server's file being out of sync.

I am creating a little cluster thing and documenting how to build it.
If dnsmasq has a simple way of doing something, it will make my docs
of the process easier.
