I'm also tinkering with SEARCH in /etc/sysconfig/network-scripts/ifcfg-eth0.

More precisely, I need to add two domains to the search list, and override the
dhcp-provided dns server, like so:

SEARCH="domain1.com domain2.com"
DNS1=1.1.1.1
DNS2=2.2.2.2

To test it, I do this:
# ifdown eth0
# rm /etc/resolv.conf*
# killall dhclient
# ifup eth0

As a result, I get this:
# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 1.1.1.1
nameserver 2.2.2.2
search domain1.com

# cat /etc/resolv.conf.save
; generated by /sbin/dhclient-script
search domain1.com domain2.com
nameserver 192.168.217.2

As you can see, typing 'ifup' creates resolv.conf and resolv.conf.save.  The
resolv.conf has the correct (overridden) dns servers and only one search
domain, while the resolv.conf.save has the wrong (dhcp) dns server and the
correct search path.  

What's crazy is that the correct information is all coming from the same file
(/etc/sysconfig/network-scripts/ifcfg-eth0).  I even tried extra quotes:
SEARCH="'domain1.com domain2.com'", the quotes show up in resolv.conf.save but
not in resolv.conf, which is unaffected.

I wonder if this bug is why someone decided to start over with NetworkManager.
