Example of what you are talking about?
Its easy to sort stuff but you kinda have to know the sytax of the
statement first.

Sure- example-

within the cisco config, we have a series of ip host commands, i.e.-

ip host a2e 10.5.1.17
ip host a1e 10.5.1.18
ip host nsp 10.6.1.15

Believe it or not (and I wasn't aware IOS did this), but the order that
these commands appear in the config changes based on what host was used
last.

So, if I used the nsp hostname from the CLI (by typing "nsp" or "telnet
nsp"), the config would then look like-

ip host nsp 10.6.1.15
ip host a2e 10.5.1.17
ip host a1e 10.5.1.18

This of course represents a DIFF.

What I'm looking for is a way to ignore these types of DIFFs- not only for
the mailer broadcast, but ignore them completely, so that the version number
doesn't get incremented.

Thanks again.

There is some stuff in rancid to order "ip host line\d+" commands,
but it looks like this ip host stuff is more than just the line\d+
stuff, so try this patch & let me know if it works.

That did the trick- thanks much, appreciate the quick response!
