[0]Oh, weird party trick: some time just before nuking a system to do [0]a fresh install or something, rm /sbin/init, halt and reboot and watch. [0]That is certainly not what other UNIX systems do... [1]It is most certainly what other Unix systems do. Someone mistakenly [1]wiped out init on an Ultrix box at my University (they thought they were [1]deleting an old user account, rm -rf *), and it required a complete [1]re-install to get things working. I wiped out init in the 386bsd days, [1]but luckily I was able to recover by installing a new version of init [1]off the install floppy. Actually, most UNIX (and XENIX) systems simply say "panic: no init" instead of doing what we do. Even in this state, you can recover with a boot floppy (if you have one). Otherwise, it is reinstall time. (Kids, don't try this at home.)
