[Merge] ~itrue/livecd-rootfs:add-nemos-support-v2 into livecd-rootfs:ubuntu/master

[Isaac True]

I added the lsb_release part as SUITE is not set when building on Launchpad:

if [ -z "${SUITE}" ]; then
    SUITE=$(lsb_release -c -s)
    echo "SUITE not set; defaulting to ${SUITE}"
fi

Building on lcy02-amd64-091.buildd
SUITE not set; defaulting to lunar
