/etc/init.d/rcS doesn't wait for init scripts to finish

Description

/etc/init.d/rcS (from base-files) should wait for init scripts to finish, not just leave them running in the background (the '&' character at the end).

This is causing problems on system shutdown, as the system halts or reboots before everything is terminated, even before the root fs is unmounted (which leaves it in an inconsistent state, often while being written to).

Considering system boot, the console shell appears before booting is complete, and a useless "logger" process is left, consuming memory.

The '&' was added as a hack; without it boot will never finish as the subshell in /etc/init.d/rcS is waiting a shell job to complete. The shell job concerned is "hotplug2" in /etc/init.d/boot.

My patch fixes running hotplug2 so that a simple background process is created, not a shell job. This allows the subshell to terminate on startup, we can now safely wait for all init scripts.

It appears some users want the shell to appear immediately on boot. So here is a patch which explicitely leaves the scripts running in the background for startup only.
