Description of problem:


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


How reproducible: 100%


Steps to Reproduce:
1. Configure dhcp with option dns-domain "domain1 domain2";
2. Attempt install that uses network and dhcp configuration
3.
  
Actual results: Anaconda goes into an infinite loop that you can't break out of


Expected results: Reverse host name lookup should succeed and proceed from there


Additional info: The syntax for dns-domain that is listed above, while not
strictly correct, is handy for passing a complete search list of domains to dhcp
clients instead of a single domain.  This syntax works 100% under Fedora Core
once the installation is done, it only fails under anaconda.  Mac OS X doesn't
quite handle it right, but oh well.  Windows XP is hard to tell, I'm not sure it
ever uses domain search information from the dhcp server.
