[SLUG] RedHat 6.1 Losing DNS setup (/etc/resolv.conf)

I just found a problem that i would share with you all.

When a ppp connection was re-established (in this case big pond direct) the
/etc/resolv.conf was overwritten with the Telstra supplied DNS (via ppp
negotiation).  In effect disabling the caching DNS installed and telling the
system to refer to Telstra's server for all DNS lookups.

After fishing through the network-scripts I fouind I needed to add a line to
the /etc/sysconfig/network-scripts/ifcfg-ppp0
PEERDNS="no"

It is documented in the /usr/doc/initscripts-4.63/sysconfig.txt
I suspect this is only with an updated RedHat 6.1 (as there is an update for
the init scripts)

It happened on another site so now I know what to fix I can re-visit it.

regards, Ian
