Because none of the userspace daemons would be running. Saying
"init=/bin/sh" is a great way to get the root filesystem and a command
prompt and *nothing* else - the init scripts are never run, so no other
filesystems are mounted, no kernel modules are loaded, nothing like
that. The kernel loads, brings the console up to a known state, and
then forks off to the shell. Normally, of course, it would fork init,
which would then read inittab and then the startup scripts.
