The hostname is added to localhost entries in /etc/hosts because some

Read /etc/hostname?
Adding "localhost" entries to /etc/hosts does nothing for applications
that require an entry with the hostname in /etc/hosts, *unless* the
hostname is "localhost". Now as Networkmanager (apparently) sets the
hostname to "localhost", I can see why Networkmanager wants to add
"localhost" to /etc/hosts afterwards. But hey, we might as well set the
hostname to everyone.loves.networkmanager, then add *that* to /etc/hosts
and run into problems.
Please note, that /etc/hosts has nothing to do with the hostname, it's
only a way to statically (and locally) add things to the resolver.

I don't think adding or not adding them to /etc/hosts makes any
difference. I'd guess that calling sethostname() causes problems.
