+#
+# Create a "bank" of tap network devices that can be used by the
+# runqemu script. This script needs to be run as root, and will
+# use the tunctl binary from a Poky sysroot. Note: many Linux distros
+# these days still use an older version of tunctl which does not
+# support the group permissions option, hence the need to use Poky's
+# version.
