You may want to add a default case, calling the fail() function:
case $listenif {
'eth0': $listenip = $ipaddress_eth0
...
default: fail("Bad value for \$listenif: ``$listenif''")
}
That way you will get a clear error message instead of just strange
behaviour when you, two years from now, happen to set $listenif to "eth7".
