Please CC; I'm not subscribed. I recently heard about your efforts, and am glad to see them. Looking over how things were doing, I noticed you Suggest cupsys-bsd.
I'm flattered, but I don't think that this is correct. The current standard print system for Debian is still good ol' lpr, and people wanting to declare a relationship with a print system should probably reference that package, rather than cupsys-bsd or lprng. (Unless they need an explicit dependency, of course, but I don't think that's the case here; most people who need to depend on CUPS client capability depend on libcupsys2.) This will ensure that lprng fans aren't asked to remove their beloved print spooler in favor of some ungodliness. :-) CUPS people don't need to fear this; cupsys-bsd Provides lpr, so all will be well. -- Jeff Licquia, maintainer of cupsys for Debian
