Hi Josh.
This was added in Django 1.9 here
https://github.com/django/django/commit/fc2147152637e21bc73f991b50fa06254af02739
It leverages the extends tag, re-using the same template name:
# myapp/templates/admin/base.html
{% extends "admin/base.html" %}
{% block footer %}this site is restricted, blah blah legal text blah{%
endblock %}
So as long as myapp/templates are loaded before contrib.admin's then it you
should see the result you're after.
#15053 <https://code.djangoproject.com/ticket/15053> references
django-overextends as the influence.
Kind Regards,
Carlton
