[pkg-dhcp-devel] Bug#609851: isc-dhcp NMU dhclient-script patch

[Tim Heckman]

Good news and bad news.  The good news I have a patch to
"/sbin/dhclient-script" that fixes this.  The bad news is that is causes
/etc/init.d/hostname.sh to fail at boot.  To have the hostname be set by
dhclient, with this patch, "/etc/hostname" must exist but have a length of
zero:

+            "$host_name" != "$old_host_name" ]; then

        fi

         if [ -n "$old_ip_address" -a -n "$alias_ip_address" -a \

The hostname.sh issue isn't critical, but it's still a bit unsettling to
see init scripts unhappy at boot.  I'll work on something for
"/etc/init.d/hostname.sh" so that it doesn't fail on boot.  Things just
can't be easy, can they?
