1. FYI, There is a short, direct upgrade guide that should be referenced before upgrading to 1.6:
<http://www.gentoo.org/proj/en/desktop/x/x11/xorg-server-1.6-upgrade-guide.xml> It refers to another, short upgrade guide that should definitely be reviewed before proceeding: <http://www.gentoo.org/proj/en/desktop/x/x11/libxcb-1.4-upgrade-guide.xml> 2. The second guide uses a lot of "one-shot" emerges; could anyone please explain why I'd use a one-shot? ISTM that if a package is on my system, I'd want it routinely updated. If I need it only once, then instruct me to unmerge it after it's done!? TIA
