Description:

This package contains the legacy scripts for activating & deactivating of most
network interfaces. It also provides a legacy version of 'network' service.

The 'network' service is enabled by default after installation of this package,
and if the network-scripts are installed alongside NetworkManager, then the
ifup/ifdown commands from network-scripts take precedence over the ones provided
by NetworkManager.

If user has both network-scripts & NetworkManager installed, and wishes to
use ifup/ifdown from NetworkManager primarily, then they has to run command:
$ update-alternatives --config ifup

Please note that running the command above will also disable the 'network'
service.
