As is turns out, I do have a follow-up question. Daniel, did you mean that emerge -e really picks up ALL packages or just the ones that I have currently installed? I ask because when I tried your suggestion, 'emerge -e world' failed on a package that I had never chosen to begin with and couldn't trace back to a dependency on any I had chosen. Of course, I too new to this to be sure but clarification would help. The man page is a little cryptic in its explanation. I would also like to ask the person who responded with saying that they caught the emerge output to a file and simply edited out the successes so they could restart the failures easily, how they did the catching. Simply redirecting the output seems to catch thousands of lines of compile info etc that is simply too weighty to edit out by hand. Thanks,

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
