ifupdown is not installed by preseed, while iproute2 is installed

[Darren Baginski <kickbsd@yandex.ru>]

Hello!

I have been installed Debian Jessie using pressed, after successful install and reboot I realized that eth0 is down and ifupdown package was missing. Why ?
Same preseed file on wheezy installs ifupdown by default.

Then I tried to do

root@localhost:~# apt-get install ifupdown

The following packages will be REMOVED:
  iproute2
The following NEW packages will be installed:
  ifupdown iproute
0 upgraded, 2 newly installed, 1 to remove and 0 not upgraded.

After this operation, 74.8 kB disk space will be freed.
Do you want to continue [Y/n]?

Looks like iproute2 was installed which
a) conflicts with ifupdown for some reason (why ? I guess it functionally can replace older iproute ) 
b) can't initiate interfaces alone (perhaps jessie is using newer network initialization method of which I'm not aware)


Thanks!
