Would a timestamp check help ? You can have several triggers of
course but the triggers system is not designed to have very many of
them. If you expect to have a dozen icons subdirs eventually then a
trigger for each one would be overkill.
Also, if you have only one trigger you can know that dpkg won't call
your postinst for triggers more than once unnecessaarily.
