Ed Schouten 53cb00a92b Sort `mount -p' output by name before checking for any differences.
I noticed on a system at home that restarting named(8) causes the
/var/named/dev mount to be moved to the bottom of the mount list,
because it gets remounted. When I received the daily security email this
morning, I was quite amazed to see that the security report listed the
differences, while it was nothing out of the ordinary.

If we just throw the `mount -p' output through sort(1), we'll only
receive notifications about changes to mounts if something has really
changed.
