I was using following command in FreeBSD 6.2:

In FreeBSD 7.0 I got an error:
# ifconfig lo1 create inet 172.16.16.2 netmask 255.255.255.0
ifconfig: inet: bad value
But it is working splitted in to two commands:
# ifconfig lo1 create
# ifconfig lo1 inet 172.16.16.2 netmask 255.255.255.0
Is this expected behavior or should I file a PR?
This expected. There's some argument it's wrong, but filing a PR is
unlikely to cause it to change any time soon.

Why? The same with creating gif-tunnel, now I need to invoke ifconfig
twice, once for 'create' and once for other tunnel parameters,
whereas for RELENG_6 this works: 'ifconfig gif0 create tunnel 1.1.1.1 2.2.2.2'

This breaks existing setups/scripts. This is POLA issue.
Why was it broken?
