Its difficult or impossible to save the state of the kernel and restore th= e=20 shadow copy. Its probably easier to save the state of a user program instea= d=20 and restore it should the process dump core. Q to you:- what do you plan to= =20 do when saved copy of kernel contains information of a process that exited= =20 after copy was saved but before the kernel panic'ed required to be restored= ? regards -kamal
