Portage suddenly wants to install net-dns/bind so it can update bind-tools from 9.16 to 9.18. I've always had bind-tools installed, but it has never required that I install the bind server and its dependencies (for which I have no use). Older versions of bind-tools didn't require bind. The ebuilds for bind-tools 9.20 that I've found at on overlays don't require bind.
What's so special about bind-tools 9.18 that it has to have bind installed? Is there another package that will provide a command line dns lookup tool that can be used for troubleshooting that doesn't require me to install a DNS server all of its extra faff? -- Grant
