Hi Adam,
You can have as many FQHNs in your hosts file as you wish for the same
device. This is not a problem. But only for *real* devices. The lo
device (127.0.0.x) should better be left alone and only have assigned
'localhost'.
There's plenty of software around (Oracle, Zimbra) which will go tits-up
if you assign a genuine hostname to 127.0.0.1 in certain DNS
configurations.
I prefer a simple '127.0.0.1 localhost'.
Sometimes you find an entry '127.0.0.1 localhost localhost.localdomain'.
I don't know who invented the localdomain suffix, but it seems just as
silly to me.
