So, I got curious about his claim : "that change to resolv.conf adding 
the search line [search hosts, nameserver] has been required since red 
hat 5.0 in 1998".
(The bracket addition is mine)
I'm not using RHEl-based systems a lot so I may be wrong, and there's 
not a lot of material left from the 1998 web, but the resolv.conf file 
*looks* identical in RHEL-based systems, at least nowadays.
I quickly browsed a few RH help pages about resolv.conf, but couldn't 
find his claim.
I then searched for "search hosts, nameserver" on search engines 
(-with- the quotes, to only get full-match results).
Either I get no results or ... wait for it ... it *ONLY* gives me 
results where Gene posted !
So Gene, can you tell us where you read this ?
