Subject[BUG] execve("/bin/sh"...) in init/main.c
Date
If init cannot be executed, the init(.) function in init/main.c falls back to 
sh and calls execve("/bin/sh", argv_init, envp_init).

But if there is no "init=" in the command line, argv_init can contain
something (most likely the "auto" preprended by lilo) and the shell will
terminate immediately. (parse_options(.) does not handle this case since it
does not find "init=").

I used the simple patch below to correct the problem.
