Acting under the double influence of lack of sleep and pain killers in hopes of sleeping sometime in the future, I entered the following command: emerge system -s The error message returned was "emerge: please specify a package class ("world" or "system") or individual packages, but not both.".
Followup: Shouldn't "emerge system -s" or "emerge world -s" return a valid result? Somebody might wish such a list without having to do an "emerge -s" on each individual package.
This is not really important as I see no reason for it at all. Can you give a reason that you'd use this? A search on every package would take an extraordinate amount of time, and it would not really produce information that people would find useful. --pretend provides the most consise and useful listing. If you have a better reason, reopenthe bug.
