[Bug 476491] [NEW] [karmic regression] Hostname not set by dhclient when no hostname defined in /etc/hosts

[Stefano Rivera]

Public bug reported:

While this would appear to be the same as bug #90388, we've never had an
issue in any release before karmic, if the only IPv4 data in /etc/hosts
was "127.0.0.1 localhost".

In jaunty and previously, on bootup with no hostname specified, the
hostname would be "(none)". In /sbin/dhclient-script, there's the
following:

set_hostname() {
    local current_hostname=$(hostname)
    if [ -z "$current_hostname" -o "$current_hostname" = "(none)" ]; then
        hostname "$new_host_name"
    fi
}

However, with karmic, the system will boot with a hostname of
"localhost" and the above rule will never fire.
