You may want to set this in your make.conf file: FEATURES="parallel-fetch" What that does, as soon as you start the emerge process, it starts to download the needed files. It doesn't wait until it is ready to work on the package to download it. I've had that set for so long, no idea if anything has changed as far as defaults. I just know it works that way here. If you set that, you should be able to sync, start emerge and when it downloads the last files/tarballs it needs, you can then remove your internet connection. You can monitor that with this command. tail -f /var/log/emerge-fetch.log Hope that helps. Dale :-) :-)
