There's two pdf's and one command I use "often" :)
The redhat 5.3 deployment and installation pdf's (or the online versions)
and:
# find /usr/share/doc/ -exec grep "PEERDNS" '{}' \; -print
PEERDNS=yes|no
file if PEERDNS is not set to "no".
/usr/share/doc/initscripts-8.45.25/sysconfig.txt
honor PEERDNS=no for pump and dhcpcd too (#18619)
DEFROUTE defaults on; PEERDNS documented and defaults on
/usr/share/doc/initscripts-8.45.25/ChangeLog
Now you know what doc to read...
Also:
man -K PEERDNS
But that's generally a slow and last ditch effort even after google:)
It also never helped with this string but its useful to know.
