Description of problem:
As a result of bug #62127, redhat-config-network application 
doesn't add PEERDNS='no' to ifcfg-XXX file when the option 
"Automatically obtain DNS information from provider" is left 
unchecked. (It adds a line PEERDNS="yes") when you check this
option, which is ok)

The scripts ifup-post, ifup-ppp) check for "$PEERDNS" != "no", and 
since PEERDNS is NULL the conditional gets true and the 
/etc/resolv.conf is overwritten. I have tested this
with dialup and DHCP connections

The script ifup on the other hand checks for "$PEERDNS" = "no" 
in order to add the PUMPARGS and DHCPCDARGS to prevent the
overwrite of /etc/resolv.conf, it should be changed to 
"$PEERDNS" != "yes"


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Start redhat-config-network
2.Add or Edit a dialup, dhcp or boop device, try the option 
  "Automatically obtain DNS information from provider" unchecked
  and checked.
3.Enable/Disable this device to see changes in /etc/resolv.conf

Actual Results:  The ifcfg-XXX file doesn't contain a PEERDNS='no' 
line, and the /etc/resolv.conf file gets overwritten when you enable
the device.


Expected Results:  When I left uncheck the "Automatically.... provider" option,
I expect to use my own DNS servers and /etc/resolv.conf should not get
overwritten everytime.

Additional info:

The bug 62127 changes the behaviour of redhat-config-network
so it doesn't add the line PEERDNS='no'.

Maybe we should get redhat-config-network fixed instead of the
initscripts ?
