To put this a little more plainly: It is a complete install of
Archlinux, just on a cd instead of a hard drive. The RAM usage will be
as minimal as a bare-bones Arch install.

Now, many people may be thinking "but what if I want to remove my cd
from the drive?" - funny enough, that should work ok unless you need
to access the "disk".

You *can* add the "copytoram" boot param (yay grub) to have the
squashfs image copied to ram first. I'm not sure of the actual image
size anymore, but that should soak about 100-150 megs of RAM extra.

One of the next steps would be to actually add another parameter to
unpack the squashfs image into ram. This would take... oh, I dunno
300-400 megs of RAM?
