Yes, since "/etc/network/if-*.d/upstart" scripts are shell scripts, you can use an environment variable such as $HOSTNAME.

Here is what I recommend: set it first with the value you want to be sure of what is inside, like this:

HOSTNAME=`hostname -s`

exec someexecutable -n "$HOSTNAME""_bb"

Thanks. That worked. You however have to wrap it in a `script/ end script block` to have upstart execute it. – RickyA Apr 02 '13 at 15:50
