Bug#245535: hw-detect: Fail sometimes if /etc/network/ is missing

[Petter Reinholdtsen <pere@hungry.com>]

Package: hw-detect
Version: 0.84
Tags: d-i patch

The package hw-detect fail sometimes, when this code is executed and
/etc/network/ don't exist:

   if [ -n "$newdevs" -a -n "$cardname" ]; then
        for dev in $newdevs; do
             echo "${dev}:${cardname}" >> /etc/network/devnames
        done
   fi

A description of the error is available from
<URL:http://bugs.skolelinux.no/show_bug.cgi?id=719>.  The fix is
probably to make sure /etc/network/ exists before appending to the
file.
