[lug] Why is it SO easy to destroy cloud environments?

[David L. Willson]

rm -rf is terribly slow, leaves the server running, and leaves potentially undesired partitions.

# sloppy un-tested, incomplete meta-code

for each server in servers_to_clear(); do
ssh server
    for each filesystem in local_filesystems(); do
        dd if=/dev/zero of=$filesystem bs=4M count=256 &
    done
    for each disk in local_disks(); do
        dd if=/dev/zero of=$disk bs=4M count=256 &
    done
    # need another imaginary function to remove this servers entry from DNS
    while dd_is_running(); do sleep 30; done
    poweroff
done

There, that should do it.
