+# TODOs before actually using this
+# - change root auth to use adminpassFile
+# - figure out how to enable redis caching
+# - figure out how to use multiple pools (do we need this?)
+# - how to enable ldap?
+# - move this into a container (only reason it's not in one already is
+#   to make testing easy; just run the following for a local test:
+#   `nixos-container create nextcloud --config-file nextcloud.nix`
+#
+# Additional notes:
+#  - there is a services.nextcloud.phpExtraExtensions, which may be
+#    useful for this, but it's only in nixos-unstable for now
+#  - there's a services.nextcloud.autoUpdateApps – do we trust nextcloud
+#    enough to enable it, or will everything break if we do?
