Public bug reported:

On a VM with many interfaces it is possible that udev is slow. This may
lead to the situation that 70-persistent-net.rules is being written to
by cloud-init while also being written to by the net rules generator (75
-persistent-net-generator.rules). This may lead to interleaving,
duplicate definitions or incomplete data.

The user can already specify an optional rules file with the
"netrules_path". However this will not have any effect when the file
gets written as udev is not re-triggered. When the user configures a
custom file (which logically should be something like 71-persistent-
net.rules) cloud-init should trigger udev to add any new rules the code
might have written.
