- You have an old init. With the cable out getty fails to open the port so
- exits. Init sees the getty has exited and immediately restarts it. Getty
- fails to open the port and exits... etc...
-
- The newer inits (certainly my init in the bootsys3.taz suite and Miquels
- init, possibly poe's simpleinit too) trap processes that respawn more than a
- certain number of times in a given period and disable them (see the
- documentation). Get one of these.
-
- (There are many other features to the bootsys3.taz stuff too).
