[bug#45047] [PATCH 0/2] Add service for radicale.

[Jonathan Brielmaier]

Hi,

this is a simple version of a service for radicale, a CalDAV/CardDAV server.
Password encryption with bcrypt is not working yet.
For the future I want to add the plugin for auth via dovecot. That's for another
patch series...

With the default configuration I confirmed that the service work as expected...

Jonathan Brielmaier (2):
  gnu: radicale: Update to 3.0.6.
  services: Add radicale-service-type.
