Note that while there is no DOMAINSEARCH, DNSDOMAIN needs to translate into something (domain or search directive), and only one of those will be honored by the resolver (they overwrite each other, per the specification).

This would appear to be an issue in d/net-interface-handler, which currently ignores the DNSDOMAIN value.

There is no documentation in this file indicating what variables are expected or used...

But it seems most reasonable for DNSDOMAIN to translate to domain and DOMAINSEARCH to search, semantically?

Revisiting bugs that were triaged but dormant for 6 months I think we have to realize that this wasn't at the top of anyones todo list.

I didn't hear anything else about it and don't see this bug win against others up in the queue atm.
So to be honest we should reflect that in the bugs importance and lower it to match what happens.

@Lamont - since this casme from Maas, how did this continue for Maas? Is it just a remaining low-prio issue or more important than it was handled so far?
