Changing output from error to info

We have received a suggestion for a change to how we output some information (see below)
I agree that this information is likely to be more of an "info" than an "error" but I'm reticent about
changing and possibly breaking any scripts that may be looking for it.

My current thought is to make the change in 4.3 (4.3.2) which is probably not widely deployed yet,
but to leave it as is for 4.1 and 4.2

I'd be interested in hearing if people are looking for this string and if such a change would present
any problems for them.

If I don't specify interfaces to listen on, dhcpd listens only on 
interfaces, for whose it finds subnet declaration in dhcpd.conf.
For each interface where's no corresponding subnet declaration, dhcpd 
spits out an *error*
"No subnet declaration for <interface>. Ignoring requests on 
<interface>. If this is not what you want, ..."
This should not IMHO be an *error*, but only *info*, because there's 
quite a big chance that this is exactly what user wants.

If there's no matching subnet declaration for *any* interface dhcpd 
spits our fatal error
"Not configured to listen on any interfaces!"
which is all right.
