Interestingly, though I got around this problem by stomping on netatalk,
it is still broken and causing problems with amavis.

Symptom: 

# hostname 
  returns the subdomain (this machine is a subdomain - this is as expected)

# hostname --fqdn [-f]
  returns hostname: Name or service not known

/etc/hosts looks fine, as does /etc/hostname

This stopped working because of a dist-upgrade, no changes to any
configurations.

How does "hostname" work?  Why could it be barfing?  Thanks again.
