Thanks, I see there are many ways to do this and decided on the copy
by date with an appropriate editfiles just for the needed line. That
seems the simplest. I also see that the EmptyEntireFilePlease option
would work.

Regarding short_hostname, on my system '/bin/hostname' returns the
FQDN. If I try using $(host), I just get the FQDN. Is that normal?
That's why I'm using my own variable.

I'm a little confused on how to use template files. Since the template
file is on a server, how do I get it part of the editfiles? I'm only
familiar with using 'server=' in copy:. Do I need to copy the file
over first? If so, how do I make sure to do that before an edit (and
if possible, to avoid worrying about this ordering)?
