Should be done in userland (its handled by init), and the kernel should not have to know about these kinds of things. Then again if things were so fubared that a process with the watchdog died, then you're not bound to be able to shutdown cleanly anyway. > Also, I am very interested on being able to retreive current system > time in a human-readable form (YY/MM/DD hh:mm:ss).

Also should be done in userland, why would you need to have pretty printed time for anyway? Regards, Zwane -- Kernelnewbies: Help each other learn about the Linux kernel.
