Well, for those files that are actually supposed to contain DEPEND atoms that is probably true. I haven't checked the whole man page and all files it lists to see if it places any restrictions on some specific files therein, so I'm a bit timid to claim full "no limits" either. But for package.keywords it didn't mention any limits and I'd believe the others don't have them either. :) Still, the best identifier of the allowed syntax is probably portage itself. Make a typo in files under /etc/portage and portage will tell you next time you emerge -pv something or emerge -av something. And it also breaks in a quite predictable fashion when it reads your typos in those files: it will just drop the lines it doesn't understand (while also printing warning messages) and then dutifully proceed to next line. So if ever in doubt, you can try it and see what portage's parser thinks about your "fuzz-test". :) > This is my (mis)conception, although, as you have suggest, > there are (gentoo) cultural norms that do suggest > certain boolean operations should not be used, > in say for example, package.keywords? Not sure if by cultural norms you're referring to something I'd rather label as "best practices"? :) But then again, there are best practices for bleeding edge folks and best practices for "stability is paramount" folks and they may overlap, but most likely they aren't quite the same. > I'm mostly running stable with exceptions being enabled > via the /etc/portage file structure.

Then, again, you probably don't want the >= as it will unmask the latest testing version currently available, plus in future any new testing grade versions as they get added to portage tree. What you want is either = or ~. (And do note that ~ at the front of a DEPEND atom means a different thing from the testing keyword in ~arch). But it is all up to you to decide, you're the commander'n'chief of your own boxen. -- Arttu V.
