==== "stage4"/box/iso building ====
* [http://packer.io packer.io] can be used to build stage4 (containing a kernel) images and seems to work for gentoo. Packer often gets used to build Vagrant boxes.
** [https://github.com/pierreozoux/packer-warehouse/blob/master/var-files/gentoo/generate_latest.sh gentoo script from packer-warehouse] used with packer to create a minimal gentoo vagrant box
