if you do not set these:
region defaults to "us-east-1"
security group defaults to "gentoo-bootstrap" and it will be created if needed
key pair defaults to "gentoo-bootstrap_$region" e.g. gentoo-bootstrap_us-east-1

The key pair will be created if needed.

================================================================================
Updates
================================================================================

Gentoo updates should normally be done manually in case an incorrectly done
upgrade may render the system unusable. The purpose of these scripts is to do
the same update across regions quickly.

The plan is to manually do the update in one region and record the actions
in ${architecture}/update_gentoo.sh. Once done these scripts can be used to
replay it in the other regions.
