This will also update direct dependencies which may not be what you want. In general, use this option only in combination with the world or system target. I accept that this is somewhat unclear, but to explain it fully would take more space than a man page really is for. But anyway, the 'best' version available is mostly determined by the arch masks, which are determined by the developers. Best in this case is a somewhat poor choice of words, but at least indicates the subjectiveness of the determination. In any case, a few examples: media-video/mplayer Available versions: 1.0_pre6-r4 1.0_pre6-r5 1.0_pre6-r6 1.0_pre7 Installed: 1.0_pre7 Homepage:http://www.mplayerhq.hu/ Description: Media Player for Linux All available versions of mplayer are stable, so the 'best' version is the most recent stable. media-libs/xine-lib Available versions: ~1_rc6-r2 1_rc8-r1 1.0-r2 1.0.1-r3 ~1.0.2 ~1.1.0 ~1.1.0-r1 Installed: 1.0.1-r3 Homepage:http://xine.sourceforge.net/ Description: Core libraries for Xine movie player in this case, if one was using stable arch, and had not activated unstable for this package (as I haven't), the best version is the most recent stable (1.0.1-r3), which is not the most recent version. However, if one was using ~arch, or had activated unstable for this package in /etc/portage/package.mask, then the 'best' version would be 1.1.0-r1, which is the most recent revision, but not in stable Portage. media-video/ati-drivers Available versions: 8.8.25-r3 8.10.19 8.12.10 [M]8.13.3 [M]8.13.4 8.14.13 8.14.13-r1 8.14.13-r2 [M]8.14.13-r3 *8.16.20 Installed: 8.14.13-r2 Homepage:http://www.ati.com Description: Ati precompiled drivers for r350, r300, r250 and r200 chipsets Now in this case, the 'best' version is the most recent stable. The second most recent version (8.14.13-r3) is hard masked, but if I unmasked it with /etc/portage/package.unmask (and possibly also /etc/portage/package.keywords), then Portage would consider it the 'best', insofar as it would attempt to install it if I upgraded the drivers. Of course, the very fact that you have to manually unmask the packages should give you pause as to whether you really want to consider this the 'best' for you. The very most recent version (8.16.20) is 'not available' -- meaning that it will never be considered the 'best' version until it returns to Portage; masking or unmasking is of no use here. I know, because I had unmasked and installed the latest drivers, which did not work well, to put it mildly, and today I synced and Portage downgraded them. I would have downgraded them manually anyway, but it was interesting to see Portage downgrade them by force despite the fact that they were still unmasked. They have so many problems that they are no longer on the Portage radar until the issues are determined to at least an extent that someone knows what to fix, and who has to fix it (Gentoo, the kernel guys if it's a kernel conflict, ATI). So, 'best' is a matter of judgement, and basically Gentoo sorts packages into categories so that you can have some context to make the judgement about what is best *for you*. If stable is best for you, then Portage will choose the stable packages (because you told it to). If unstable is best for you, then Portage will choose the unstable packages (because you told it to). If stable is generally best, but in some specific cases, unstable is best for you, then Portage will choose the stable packages except where you told it that unstable is OK. That's how it's done, mostly. HTH, Holly -- gentoo-user@gentoo.org mailing list

Hi Holly, Yes, the explanation you give is pretty much what I already knew, with the exception of the ati-drivers example. If this thread is worth continuing then it's probably around that sort of situation. So far: MASKED == not available unless we unmask a package by hand. for stable - highest available stable version would be chosen for ~arch - highest version available, whether stable or ~arch, would be chosen However, in your ati-drivers example you use the term 'not available' for the 8.16.20 version. That's an interesting choice of words since any version 'not available' would (in my mind) never be chosen by --update. It's not part of 'best' because it's not available, or so it seems to me. Best is still the highest version using stable and only changes (I think) if you do an umask in portage.unmask. I think that my question was mostly born out of sort of vague language in the man page. I don't think there's any real mystery here but I've wondered about if for awhile and just wanted to be sure I wasn't missing some great undiscovered feature of portage!

If, say, you updated a package yesterday, and someone found a critical bug in it this morning. The devs decide to hard-mask the ebuild until the problem is solved. emerge --update world will downgrade that packages to the latest one not hard-masked and fits in your profile, while emerge --upgradeonly world will skip that downgrade.

The reason I mention it is that if 'best' means 'the most recent' (which is really the only way to quantify such a subjective quality as 'best' for an automated system like Portage), the 'best' version has been known to be removed from Portage completely. Consider the case of unace, for example. The version available in Portage is quite old, and won't open newer *.ace files due to its age, but the 'best' version (i.e., the most current) is not available in Portage at all (unstable or masked; it's just 'not available', because of serious security bugs. Best is still the highest version using stable and only changes (I think) if you do an umask in portage.unmask. 'Best' is the highest version available in Portage, based on your profile (profiles mask packages or keywords based on the needs of the profile), your ACCEPT_KEYWORDS setting in /etc/make.conf (which may be ~arch, after all, so the highest version using stable would not be accurate in that case), and any adjustments you may have made in /etc/portage/package.keywords and/or /etc/portage/package.unmask.
