I know of no other easy way to do this... This comes up for us from time to time, because changes in hardware configuration (like a dead serial box) can cause the system to crash when coming up multi-user. I've always just booted from floppy and edited the inittab. A more elegant solution(?) might be to edit the binary /unix, changing the text string /etc/inittab to something else; and saving the edited /unix under a different name. Then, during the "booting unix..." initial message, give the alternate kernel name and have the hacked inittab (perhaps inittb1) include "initdefault s" or equivalent. I HAVEN'T TRIED THIS. -- Norman Kohn | ...ddsw1!nvk Chicago, Il. | days/ans svc: (312) 650-6840 | eves: (312) 373-0564
