My linux box has 2 interfaces, internal & external, with different domain names on each. While hostname and hostname-f both return the shortname that is common to both domain names, i.e. foo.external.tld (on eth2) foo.in.external.tld (on br0=bridge(eth0+eth5)) & hostname returns 'foo' & domainname returns 'external.tld'. My resolve.conf has domain set to 'in.external.tld'.
