Once again, patch to make logging a config option. Reason for this (since you asked for it): - In our setup it is easy (although still annoying) .. just edit the ebuild, add logging support (or remove it) and rebuild. For say a binary distro, having the logging is useful for debugging some times, but its more a once of, or rare thing, as you do not add or change config files every day. Sure, we can have logging by default, but many do not want ~300 lines of extra debugging in their logs is not pleasant, and they will complain. Rebuilding the package for that binary package (given the users it is targeted to) is usually not within most users grasp.
