simpleroot: rootfilesystem for installing the pmax and maybe the alpha

simpleroot: rootfilesystem for installing the pmax and maybe the alpha
on those machines you can't boot off the swap partition and thus mini-
root doesn't work - ramdisk doesn't work due to exec format problems
... so the installation will be simply dd'ing a complete rootfilesystem
image onto the disk and install the rest from there - simpleroot is this
complete rootfilesystem image - the name simpleroot comes from niklas -
thanks to him for the idea how to put it here into the distrib tree
