Old habits die hard. The maintainer of
"/etc/init/network-interface.conf" ought to be told that he's still
using ifconfig... If he's not one of these "I'll keep on using the
tools that I've been using since I first started using Linux/Unix,"
he'll change it.

For the record, "/etc/init.d/bind9" also uses ifconfig. And there may be others.

See this 2009 post [1] for the obsoletion of net-tools.

One of the Debian sysvinit/ifupdown maintainers has removed ifupdown's
reliance on net-tools for Debian 7 and has proposed that net-tools no
longer have a priority of "Important" for Debian 8 (it would then no
longer be installed by default).

Apples and oranges... aptitude was the recommended tool for installing
packages in Debian 5 and Debian 6. It was also the recommended tool
for upgrading from Debian 5 to Debian 6. apt-get is now the
recommended tool for upgrading from Debian 6 to Debian 7; I don't know
which one's recommended for installing packages in Debian 7.
