Till: as you're the initial committer of that code; any opinion ? The "serial" backend is a CUPS backend which has to run as root to correctly work. CUPS decides which backends run as roo by the file permissions of the backends. One of the backends which comes with CUPS and has to run as root is the "usb" backend: -r-xr--r-- 2 root root 34808 Mar 23 14:55 /usr/lib/cups/backend/usb This backend is still world-readable and only omits the execution bit for anyone else than root itself (644 permissions). This should also work with the "serial" backend in cups-filters. Till
