I want to add links user registration and password reset to the Horizon login page.

I have the functionaluty implemented externally and I can force teh links in by editing horizon/templates/auth/_login.html, but whenever the package updates I will loose this edit and it seems overkill to manage a forked version of Horizon to implement a one line change.

Is there a better way to inject local content then this?

We also manage a local override for the nova instance creation whihc is nice for overiding functions like that but I can't see how to override jsut text in a template that doesn't seem to generated by a function I could override.
