interfaces with more than one address?  like ppp interfaces?  using
$name would still work (would't it?).

addresses that are not ip addresses?  check $af to see if it says
"inet" before you add the route.

incidentally, having just the hostname (or address) in the hostname.###
file worked for me for wuite a while.  i didn't even have to specify

there is no parsing, since the netstart script needs to know how to
build the command anyway...
