Long names for 'option domain-name' is not written to resolv.conf while doing anaconda installation in Red Hat Enterprise Linux 5

Issue

While PXEbooting for a network install, resolv.conf is not updated with the proper domain name in the "search" field if the domain name is too long. Eg,
```
option domain-name "foo.bar.s.abcdefghijklmn.net foo.bar1.m.abcdefghijklmn.net abcdefghijklmn.net fooabcd.net example.com dev.abcdefghijklmn.net"; 
```

Resolv.conf ends up as below.

search  
nameserver <dns1>
nameserver <dns2>

This happens during the install process ONLY. The system correctly generates resolv.conf once installed.
