I need some processes to look elsewhere for DNS information from where
the rest
of the system looks.. This patch seems to me a simple solution.
We over-ride where the resolver looks for resolv.conf using an
environment variable.
This would allow me to reset this to an application specific config file
that
specifies a different server.
Anyone got better ways fo doing this?
