Perhaps the best course of action is then to modify the local mail
server (sendmail/postfix) to send out mail as the fully qualified domain
Then again, what to do in the situation of DHCP.
I guess that if mail is expected to be delivered locally then it's not a
but if you're running a bunch of servers you are going to want to send
the emails to a central location.
I guess it sounds like a problem to solve outside of the hosts file
(sorry for the thinking out loud/rambling)

OK, now this is making sense as to why it changed before. It's incorrect.
So here we are where a certain group of people want the hostname added to the 127.0.0.1
line and another group that doesn't. I tend to agree with the latter, but I would
rather explore this post F-8 than now. Removing it, yet again, in rawhide after F-8 is
released and any bugs that get opened we determine the program that's at fault and
reassign the bug to that package. It'll be annoying to users, but I think it's
best to not have the hostname on the 127.0.0.1 line.
