This is a simple stripped down version of Linux, but it is Linux
This Linux is entirely compiled for x86
Please agree to running our signed applet.
The applet must be signed in order to:
Let us create a classloader for our advanced compiling techniques (much quicker!)
Let us download the Linux disk image (saves precious applet memory!)
Despite the need to be signed, our applet is still 100% Java. No native code.
