+# vnftest-img-lxd-modify - download and modify a Ubuntu cloud image

+# The actual customization is done by a script passed with an absolute path as
+# the only single argument. The command needs to be invoked as sudo
+#
+# Example invocation:
+# vnftest-img-lxd-modify /home/vnftest/tools/ubuntu-server-cloudimg-modify.sh
+#
+# Warning: the script will create files by default in:
+#   /tmp/workspace/vnftest
+# the files will be owned by root!

+# TODO: image resize is needed if the base image is too small
