How reproducible:

Steps to Reproduce:
1. Set searchlist parameter in resolv.conf to "olddomain.com"

   "www.newdomain.com" must exist)

This is not an issue of not recognizing LOCALDOMAIN, it has to do with ping
being a SUID binary.  LOCALDOMAIN is an unsecure variable which is ignored (or
even eliminated) in SUID/SGID binaries.  LOCALDOMAIN works fine for non-SUID
binaries and ping run as root.  This is a security feature, not a bug.
