But after a person has used Gentoo a while, they figure out what process leads to the most stable update process. They also figure out what defaults to add to make.conf as well. For that, it is as Duncan and Alan describe. Both have been using Gentoo for quite a while. I been using Gentoo for a good ten years. I installed from Gentoo 1.4 I think. Here is mine in make.conf: EMERGE_DEFAULT_OPTS="--with-bdeps y --backtrack=30 --keep-going -v -j10 --quiet-build=n -1" For my updates, I use this: emerge -uaDN world The only way to get a more stable system is to do a emerge -e world and update that way. At least that has been my experience so far. If Zac adds some other nifty feature, then I may add to the above as needed. For the past few years, that has resulted in as stable a system as I can get. I do from time to time run emerge -e world just for giggles when I have something acting odd and can't put my finger on the issue. Sometimes, that fixes it, sometimes not. Again, most of this comes from experience. The handbook explains it then the user figures it out from there. My $0.02 worth. Dale :-) :-) -- I am only responsible for what I said ...
