Store data in /opt?

[Eeems]

Perhaps a similar bind mount to toltec-dev/toltec#213 should be done for the templates?

This was added to the toltec package itself, but perhaps having the tool be a bit more aware of the bind mount would still be a good thing? Maybe having a method to restore back to the original data and handling juggling the bind mount and data copy?
