Just a guess: System.keychain contains the trusted root certificates (Verisign, Thawte, etc.) If mDNSR is doing wide-area Bonjour stuff, it might be using SSL (or other public-key crypto?) to connect to a remote DNS server.

If this is true, though, it's weird that mDNSR would be sandboxed to prevent access to this file. Maybe a bug?
