Has anyone bundled "nsupdate" into a snap?

Client wants to use “nsupdate” (part of “bind9-dnsutils” package) to join their UC20 device to the corporate network (it’s what they’ve used all this time before moving to UC20 and they would prefer to keep using it).

Has anyone bundled nsupdate into a snap and, if so, can explain what plugs/interfaces would be involved? As it’s not immediately obvious from poking around the builtin interfaces.

Or is there a better way to do this?
