When installing Gentoo, I normally use stage2 or stage3 for the installation. Some time ago though, I was curious what stage1 had in store for me.
So I executed the bootstrap script, when the documentation guide ordered me to. Halfway during the installation, my computer had some troubles connecting to the server when it wanted to get an ordinary package required for a succesful installation. The attempt to download the package from the server resulted in a connection error. Connection errors happen here so once in a while - not much to do about it. The script ended at this download-failure, no new packages were tried to download and installed anymore.
So I executed the script again, asuming that it would start where it left of. But no! It started to download and install all packages over again - thus also the packages that already were compiled the last 3 hours.

Now I'm wondering if it's not possible to adjust the script in a way so that it can detect if there are already some packages compiled by the script so that the script automaticly goes further where it left of last time.

Can somebody give me information about this? Is the script ment to act this way? Is it something that should be fixed? Please let me know
