Is your feature request related to a problem? Please describe.
Our environments heavily use ndots feature of various resolvers. Unfortunately, we can't find a way to inject that option into /etc/resolv.conf, because it gets overwritten by OPNsense right away.
Specifically, this is on systems with unbound service disabled, so we can't leverage that service in any way.
Describe the solution you like
We'd love to see an additional OPNsense configuration option for 'arbitrary' resolver options. In our case it's ndots:4, but I imagine there are other options other people would be interested in injecting.
Describe alternatives you considered
We've tried a custom dhclient hook via /etc/dhclient-exit-hooks, which is executed, but any changes we make to /etc/resolv.conf get wiped right away.
Thank you in advance!
