The Alias and WantedBy directives can accept all valid unit types when using the systemctl from systemd. And since the systemctl script should match the behavior of systemd as much as possible, add the current set of unit types listed at http://www.freedesktop.org/software/systemd/man/systemd.unit.html to the Alias and WantedBy directives. The deficiency was exposed when trying to use: Alias=default.target in a foo.target. No symlink was created by running "systemctl enable foo.target" during the package's postinst.
