Need to make sure and set the following variable ON in /usr/ports/multimedia/mythtv/Makefile before building plugin:
MYSQL_LOCAL
Need to edit nginx.conf and change
client_max_body_size 250m;
to 512m in versions of FreeNAS before 8.3-RC1 in order to upload/install the MythTV plugin See ticket https://support.freenas.org/ticket/1814
Need to check for existing Xvfb display, possibly from other plugin and use that, or close ours when done.
Need to create separate plugin for Xvfb/x11vnc/Fluxbox
