bugs founds while running underneath uml. One percular bug pertaining to OPTIONS was found after running a uml from the uml box then closing it again making a new root_fs and opening it again the options were missing. Haven't noticed this on the host system before. Will also need to add a c program to determine whether the host kernel is tt or skas to auto-magically determing what kernel mode to run in.
