Who's this for?
Anyone who wants to run straight Linux on their Chromium OS
device, and doesn't care about physical security. You're
also better off having some knowledge of Linux tools and the
command line in case things go funny, but it's not strictly
necessary.
What's a chroot?
Like virtualization, chroots provide the guest OS with their
own, segregated file system to run in, allowing applications
to run in a different binary environment from the host OS.
Unlike virtualization, you are not booting a second OS;
instead, the guest OS is running using the Chromium OS
system. The benefit to this is that there is zero speed
penalty since everything is run natively, and you aren't
wasting RAM to boot two OSes at the same time. The downside
is that you must be running the correct chroot for your
hardware, the software must be compatible with Chromium OS's
kernel, and machine resources are inextricably tied between
the host Chromium OS and the guest OS. What this means is
that while the chroot cannot directly access files outside
of its view, it can access all of your hardware devices,
including the entire contents of memory. A root exploit in
your guest OS will essentially have unfettered access to the
rest of Chromium OS.
...but hey, you can run TuxRacer!
