Porting OpenSolaris Project Indiana to SPARC - Part 1

Step 1 - What do you need to boot a liveCD?

Well to boot up you need a microroot. A microroot is a ramdisk image that will be loaded into memory to provide a very limited, very small, functioning user-land. A kernel, filesystem access, a few essential binaries - that's it. What then? Now that you have this machine living entirely inside its ram,  it's time to load the rest of bells and whistles. The microroot is charged with the task of locating the nest from which it flew (the CD or usb it was booted from) and to loopback mount all the goodies there as /usr, /etc, /var, and /opt. After that, with any luck, you have X/gnome up and running and you're nursing your addiction to StumbleUpon in Firefox. :)
