handbook needs "emerge -u world" reference. Problems can occure when installing from a stage image that is alot older then what is in the portage. A good emerge -u world is sometimes needed to update some system libs or files. Perhaps a good place to put a note such as this, would be directly after completing stage3. Reproducible: Always Steps to Reproduce: 1. 2. 3.
This is covered in the subsequent parts in the Gentoo Handbook, such as "Working with Gentoo".
Obviously "emerge -u world" is covered in the handbook. My point was that sometimes an "emerge -u world" is necessary directly after a "emerge --sync" when using a stage image that might be behind the deps of the portage.
I don't see why it would be needed, it doesn't break the system if you don't, and if you do it after the installation you will have at least a functional system if anything goes wrong. Afai understand, you are referring to a stage3 installation?
Yes stage3 is sort of what I'm referring to. I recently dusted off my ibook to put gentoo (stage3) back on it. I slaped on the 2004.3 image on there and began the process. dev-util/dialog kept failing in the emerge since it was needed by alsa-utils (alsamixer). I tracked it down to an old version of ncurses, after emerge -u world and getting the new ncurses the problem went away. This is my rational on why an emerge -u world. But this could also be dialog's fault for not specifying a newer version of ncurses is required. I'll leave this one your call.
