### with a few add on commands add the Sabayon Linux Overlays. 
## Wildly Inspired by  https://github.com/adrienthebo/sabayon-chroot-builder bootstrap-sabayon.sh
### goals an easy to Install Sabayon Linux LXC container, which is Gentoo Completable ,and has many uses... 
#### yet faster to update & administrate...and in many cases easier and or a GP Sabayon box suitable for a server farm LXC Virtual hosting...
#### testing packages without nuking prime Sabayon System..  ,Likewise building them & testing
###  Requires Gentoo, lxc-gentoo.in run gentoo then these few conversions ####{rootfs}
{rootfs}="${SAB_rootfs}"    
##{rootfs} # never hurts to have a fail-safe. need to keep the var in this script after lxc-gentoo.in exits
## from ${SAB_rootfs} CHROOT this script will *hotwire* the container to Sabayon spec. goal is once called it should be automatic.
Include lxc-gentoo.in

echo "Just Be sure to Name It Sabayon something.... "
