Two ways to use ChromeOS. You can use GNUroot and XSDL and run these Android apps which use a fake Chroot. But my preference is use Crouton and I use docker

Two ways to use ChromeOS. You can use GNUroot and XSDL and run these Android apps which use a fake Chroot. But my preference is use Crouton and I use docker containers and how I set up my CS sons at University. The down side is you have to leave the CB in developer mode. You also have to use rkt but works fine with docker images.
