That script is already installed with network-manager as:

/usr/lib/NetworkManager/ifblacklist_migrate.sh

Not the most discoverable thing, but it does the job.

More important is making sure people understand that this is the reason
things are booting slow for them. I'm not convinced that normal installs
lead to 'auto ethX' in /etc/network/interfaces. Only installs that
started life without network-manager will have it, which is certainly
not the norm.
