Is there any supported configuration that instructs a slave replica to first forward DNS queries to the master replica's DNS server and only if it is down, to try to resolve recursively on it's own?
The goal here is to leverage the cache of the master replica to reduce outbound queries from the slave replica. Ultimately, I want the slave replica to be as quiet/unloaded as possible and only really be used in the case of the master replica being down, if that helps the context any. This is for a small slave host in a very small network -- one where even a single replica is more than enough to satisfy the clients, but just looking to add redundancy and major version O/S upgrade paths (since FreeIPA cannot do in-place upgrades on EL and must use a replica to replicate from one the O/S major version upgrade is done -- assuming that is still the state of FreeIPA's in-place upgrade limitations -- on EL8 at least).
