272f112c98 Added new signal handler for SIGUSR2. When init receives SIGUSR2 
it closes (and leaves closed) the named pipe /run/initctl. This
can be used to make sure init does not have any files open. However,
it also means we cannot switch run levels or bring down the system.
The pipe can be re-opened by sending init the SIGUSR1 signal.

Updated the man pages for initctl and init to include this information.

This provides information on how to send messages
to the init command.
