Debian jessie самостоятельно переходит со статики на DHCP

[realvava]

Поставил вчера сервачок для тестов на привычной jessie (8.6), поставил только SSH. Упграднул всё до предела. Набил статику в /etc/network/interfaces

allow-hotplug eth0
iface eth0 inet static
address 192.168.0.8
mask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 77.88.8.8
192.168.0.1 - роутер, на котором DHCP.
Перезапустил интерфейс, машина стала откликаться по внутренней сети по заданному IP.  Сегодня уже - нет. Система не перезапускалась, сбоев питания не было. Но поскольку меня не было рядом, машинку ребутнули по-грубому - RESET-ом. Я начал копать логи.

Запущен dhclient, который и меняет ваш адрес. Прибейте процесс, либо перезагрузите сервер. А network-manager случаем не установлен?
