Making a simple installer for gentoo was actually quite fun. It's a bash script and it launches another bash script with chroot when it's time to switch to the stage3 root. I also made it interactive so when it's time to select profile or whatever I use eselect list _whatever_ | less to let user view list then prompt for choice after the less command quits. It also logs all steps to /var/log so you can check what went wrong. That's all you need, simple bash script, nothing more. It's my little installer now, pretty cool.
