From 695b3fa02ee75db9e56d3ca0d813fc3665b15df0 Mon Sep 17 00:00:00 2001 From: Chen Qi Date: Thu, 20 Jul 2017 15:33:58 +0800 Subject: dhcp: add dhclient.service Add dhclient.service. This service file mainly comes from meta-systemd, with modifications to take nfs boot into consideration. While using eth0 as the nfsboot interface, we'd like dhclient service to skip it like what ifup and connman do in sysvinit.
