I will change the printing requirements of LSB 3.2. PPD search directory will be only /usr/share/ppd. Driver packages installing to /opt or /usr/local should simply symlink their PPD directories to there.
Then I will remove the additional directories from the CUPS package. At Red Hat they also did not like the idea of providing PPD directories in /opt and /usr/local. -- [feisty] Some packages include files in usr/local or opt https://launchpad.net/bugs/94353 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
