Bug#2016: SysVinit, mount] SysVinit uses non-existant option for umount

[bruce@Pixar.com (Bruce Perens)]

> -umount -a -n
> +umount -a

This may be a "umount" bug. When you unmount the root filesystem, it is
actually the same as remounting it read-only because of special-case code
in the kernel. Umount will attempt to change /etc/mtab to match the un-mount
of root, and will fail because /etc/mtab is now on a read-only filesystem.
If it fails, does it complain? If so, the "-n" flag should be added back to
umount.

	Thanks
