Bug#238305: can not configure exim4-config due to unconfigured hostname

[Christopher Martin <christopher.martin@utoronto.ca>]

I installed a system using beta2, and encountered the same problem with 
exim4-config. The solution was to change my /etc/hosts, which contained 
merely

127.0.0.1		localhost

to

127.0.0.1		myhostname	localhost

I have since installed another system using beta3 and the 
resulting /etc/hosts was the same. I didn't change any DEBCONF_PRIORITY 
settings (I didn't actually know about this setting at all), and went 
through the various network configuration dialogs, entering a hostname, 
etc. Whatever the issue and solution is, an /etc/hosts in such a 
problematic state shouldn't be the final product of the installer, 
whatever the DEBCONF_PRIORITY of the install.

Thanks,
Christopher Martin
