Comment 68 for bug 321927

Putting udev before mountdevsubfs.sh fixed this bug for me, too!
I reordered the links manually by looking at the .postinst files of the packages containing those init scripts.
I confirm that I have had insserv installed around the time the bug appeared and that probably broke the order.

But please could a check be added to udev.postinst to ensure udev is started before mountdevsubfs and solve the bug for other users who likewise have broken their systems?
