Summary: postfix fails to install due to wrong FQDN set during
disconnect CD installation of precise beta1

Hi all,

last night I've reinstalled my laptop using the ubuntu-12.04-beta1
-alternate-amd64.iso, during the installation I've chosen to configure
my network later (laptop; no wireless at the time) and it seems that
this caused the installer to generate a "<myhostname>.(null)" entry for
/etc/hosts.

WARNING: /etc/aliases exists, but does not have a root alias.

Postfix is now set up with a default configuration.  If you need to make 
changes, edit
/etc/postfix/main.cf (and others) as needed.  To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.
