I'm trying to get cups to work at all right now... Currently, I found it needs (mostly to write) the following directories and regular files: ---------- (goes into /etc/cups/cups-files.conf) DataDir /gnu/store/1h53jmsx7gm7b2sfk0h0k6bgmp8fhv0i-cups-2.1.0/share/cups # read-only DocumentRoot /gnu/store/1h53jmsx7gm7b2sfk0h0k6bgmp8fhv0i-cups-2.1.0/share/doc/cups # read-only CacheDir /var/cache/cups StateDir /var/run/cups #FIXME FontPath /zzz Printcap /etc/printcap # written RequestRoot /var/spool/cups # written ServerBin /gnu/store/1h53jmsx7gm7b2sfk0h0k6bgmp8fhv0i-cups-2.1.0/lib/cups # read-only ServerRoot /etc/cups # ??? ---------- It starts up with that. What do we do with these file paths? Should I hard-code the /var paths? Should we ship the cups-files.conf as above in /gnu/store (there's one currently in /gnu/store, but it also specifies SystemGroup "lpadmin sys system root" and so cupsd startup fails - I tried removing it, then it starts up). For the USB printer, there's /dev/usb/lp0 with group "lp". So when I specify "Group lp" in the cups-files.conf it finds it. There's no PPD for my HP printer so I guess I'll package hplip next. Hplip has weird binary blobs for some stuff. Should we scrape them out?
