Secondly, "emerge -e system" will only recompile "system" packages, and "emerge -e world" will recompile *all* packages (including system packages). You will be recompiling system packages twice (waste of time..) As far as I know, the desired behaviour can be achieved with "emerge -e world" alone. You should confirm this with someone else though, as I'm not 100% certain. > as though you were at stage 2 of a fresh install??

Advice appreciated. Yes - this method will achieve the same results as a stage1 system. Infact, this is a method that I have picked up recently - install using Stage3/GRP so that installation is quick, then recompile all packages after that - the advantage here being that you have a usable system during the lengthy compilation. I will be trying this next time I need to install gentoo somewhere. Daniel -- [EMAIL PROTECTED] mailing list -- [EMAIL PROTECTED] mailing list
