Re: [gentoo-dev] Livecds

GOT IT WORKING!!!  thanks, a lot.

Now for a more specific question.  I'm burning tis livecd to test my installer.  I would like to get samba installed (so i can easily update the installer w/out having to make a new cd), on a basic install livecd.  What is the best way to do this?  Is ther a way to make portage emerge to the dir i'm gonna make the image from?  

For the curious:  I dcided to take my instlaller project simpler, so i just wote it as an interactive test-mode installer, but it delays all builds tillt he end so an install can be done in batch.  Soon it will be able to generate an install script for automatic installs.  I'll post more details along w/ code, etc.  once i make sure it works.
