    It can boot to command line prompt with 128MB RAM but not GUI. This 
will depend
    on the availability of a compressed loop device module and the 
ability to mount the
    cdrom at a very early stage during loading of the kernel.

    Live Linux distros typically use ISOLINUX to mount thre CD and then 
almost the entire
    kernel is loaded off the CD.

   No all the RPC services are disabled. Also once hard disk install is 
complete the
   service configuration is re-initialised so LiveCD specific 
customisations do not apply
   to a hard disk install.

   This is already avalable in OpenSolaris, I am enhancing it.
