Subject: [PATCH 05/11] dhcp-client: fix invoke dhclient-script failed on
 Read-only file system

In read-only file system, '/etc' is on the readonly partition,
and '/etc/resolv.conf' is symlinked to a separate writable
partition.

In this situation, we create temp files 'resolv.conf.dhclient-new'
in /tmp dir.

Upstream-Status: Pending
