Public bug reported:
Binary package hint: dhcp3-client
When /sbin/dhclient-script updates /etc/resolv.conf, it creates a
temporary file /etc/resolv.conf.dhclient-new.
It's not a good idea to create temporary files in /etc, they should be
created in /tmp instead.
/etc might be mounted read-only, and then /sbin/dhclient-script fails.
Or /etc might be on a device you don't want unnecessary write access on
(e.g. flash disk).
I have made a patch to fix the problem. Now it's possible to have /etc
read-only if it contains resolv.conf as a symlink to some writeable
filesystem (e.g. /tmp/resolv.conf).
