[Bug 949956] [NEW] lxc-start-ephemeral keeps same MAC address, and so same IP address, as base instance

[Gary Poster]

Public bug reported:

As smoser pointed out, lxc-start-ephemeral needs to do the same kinds of
things that lxc-clone does, such as this:

# change hwaddrs
mv ${c} ${c}.old
(
while read line; do
	if [ "${line:0:18}" = "lxc.network.hwaddr" ]; then
		echo "lxc.network.hwaddr= 00:16:3e:$(openssl rand -hex 3| sed 's/\(..\)/\1:/g; s/.$//')"
	else
		echo $line
	fi
done
) < ${c}.old > ${c}
rm -f ${c}.old

# set the hostname
cat <<EOF > $rootfs/etc/hostname
$hostname
EOF
# set minimal hosts
cat <<EOF > $rootfs/etc/hosts
127.0.0.1 localhost $hostname
EOF

We have a version that does this, and will propose it.
