Re: Unplugging the keyboard = kernel panic ?
David, this was a non-delightful feature of SPARC hardware for a long time. Probably still has it. Bitten by same "feature" two decades ago. Which reminds me, must dump the Solaris 8 pizza boxes lurking in shed so I have more room for something useful.
At least AIX, HPUX and PCs hardware was not so scream inducing. I loved the old PARA-RISC HP hardware. One could do a full backup without starting the OS using embeded firmware. Great for major OS upgrades and raw disk databases.
