Comment 27 for bug 711779

But look at the structure of the code. Wherever there's an API call to libdns_sd and supporting code for it, we have equivalent code for avahi. Code that applies to both was already there upstream.

These changes for airprint are in "neutral" territory, code that applies regardless of whether avahi or libdns_sd is used.

For that reason, they should be submitted upstream to cups (or at least suggested) so we can have some feedback on whether they're right, or whether there will be some unexpected consequence.
