# 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?
