This is hard to decide.

>From Slackwares /etc/hosts:
...
# By the way, Arnt Gulbrandsen <agulbra at nvg.unit.no> says that 127.0.0.1
# should NEVER be named with the name of the machine.  It causes
problems for some (stupid) programs, irc and reputedly talk.

From: http://lists.debian.org/debian-devel/2005/10/msg00387.html it
should be set to:

127.0.0.1       localhost        localhost.localdomain       calimero
     calimero.local
