Bug 7550

Currently the order of shutdown instructions in the run_shutdown_and_kill_processes function in init/init.c [1] is broken:

1. the inittab actions for the action type "shutdown" are run
2. all the programs are killed

One of the default inittab instructions for shutting down is "umount -a -r".  However, since it's executed before the programs are killed, it can not properly unmount some of the file systems because there may be programs still accessing them.  This leaves those file systems in an unclean state after shutting down.

I don't know if simply changing the order would be a sensible way to deal with this issue though, as they may be scripts depending on this order.
