Hello. A couple of weeks ago I filed a bug because in the Installation Handbook I found some references of the "world" set in emerge commands, as opposed to "@world": https://bugs.gentoo.org/show_bug.cgi?id=445184
The bug was closed as invalid, and I was told that: > sets with the @ prefix are a portage-2.2 feature, which is still hardmasked > and thus not documented. The fact is that I have portage-2.1.11.37, not 2.2, and man emerge says: > When used as arguments to emerge sets have to be prefixed with @ to be > recognized. One possibility is that documentation stick with the stable portage package, not the testing one (I have a ~amd64 system only). But I checked portage 2.1.11.31 (the latest stable amd64 portage package version) and the previous phrase is there, too. I know it's not a very important issue, but I'd still like to know if I'm wrong or not, and why. Thank you.
