Well, I didn't mention that Nokia's engineers invented /opt. I am just angry at them because of their decision to put everything in /opt. Maemo isn't “from scratch” distribution, it was derived from Debian. And throwing away compatibility with it is not the best choice. There is maemo-optify, of course. But sometimes it conflicts with docpurge (nice invention too): it tries to optify some files that are already purged by docpurge, producing error.
