why the IPV6 looking hostname prior to reboot?

To shed a little light on the loopback interface line, in many versions of UNIX 
utilities (not just Linux), there seems to be an assumption here and there that 
the line will look like:
	127.0.0.1 FQDN hostname localhost
and that's the way the default line you see reads. My FC9 development machine read:
	127.0.0.1 nineiron.tmr.com nineiron localhost
while the FC10 machine says:
	127.0.0.1 tenspot.tmr.com tenspot localhost

That's why "localhost" shows up twice, and at least back to FC6 it's been that 
way for a while.
