I don't mind if you go for your inital version, it's not much
duplication, but why does it look silly? I don't think we need to worry
that the <package-name> on Ubuntu (and Debian) won't have a 1=1 mapping
to the /usr/bin/<package-name>. So defining the path in terms of the
package name seems like an obvious thing to do.
