(RADIATOR) Three small(?) feature requests

A better approach for getting the FQDN in perl is to use
Net::Domain::hostfqdn().  It's a core module.

[hades:jfitz] (81) > perl -MNet::Domain=hostfqdn -e 'print hostfqdn()."\n"'
hades.pvt.primus.ca
[hades:jfitz] (82) > 

This works for me on RedHat 7-EL4 and Solaris 8-10 consistently, including
situations where Sys::Hostname was inconsistent from one platform to the
next.

According to Module::Corelist, it was first made a core mod during the 5.7.x
devel cycle, so 5.8.0 and up are guaranteed to have it:

Net::Domain  was first released with perl 5.007003
  5.007003   2.17
  5.008      2.17
  5.008001   2.18
  5.008002   2.19
  5.008003   2.19
  5.008004   2.19
  5.008005   2.19
  5.008006   2.19
  5.009      2.19
  5.009001   2.19
  5.009002   2.19

I don't actually care about the FQDN to be honest (and I suspect few 
people would be); what I do care about is consistency of behaviour.  So if 
it always returned the simple hostname, regardless, I would be happy with 
that.  It would be a backwardly incompatible change though, of course, at 
least for FreeBSD users.
