I have to add, that this change has the potential to significantly
change the shutdown order or cause a conflicting ordering, in case there
are other init scripts which declare an explicit shutdown dependency.

This will need someone to further investigate and test it.

Looking at https://codesearch.debian.net/ and searching for packages
which declare a Should-Stop or Required-Stop on udev and checking if any
late shutdown services are involved.
