Re: Why does ChromeOS still exist? It should have just been replaced with android.
"And the fact that Android (especially as Android-x86) is way closer to Linux that Chrome OS. You can run Linux in a chroot under Android-x86, and even start a X server, but with Chrome OS, you need to use crouton, which is not native enough."
To run Linux in a chroot on Android you need to root the device, subverting the device's security. Crouton is just a script to let you run Linux in a chroot on ChromeOS devices where the security has been subverted by entering dev mode. That sounds basically the same to me.
The article briefly mentioned how they're improving this for ChromeOS though, by letting you run a standard Linux distro in a container on unrooted devices. This is using the same APIs that make Docker, Kubernetes, LXC, etc possible, and lets them give you root access within the container without compromising ChromeOS's security. That sounds a lot better than what you can do on Android.
