I imagine a user(me) would do:

(service (oddmuse-service-type
          (oddmuse-configuration
           (inherit %oddmuse-configuration)
           (root "blah")
           (...))))

Is this alright? Oddmuse package is in (gnu packages web)
I am missing the service extensions, (i don't get what i need to put in
there)

Thanks
Amar

Re: Adding Services

[John Soo]

Hi Amar,

I recommend reading the manual sections on service definitions. I think that will clear up any confusion. For this configuration there are two suggestions I have:

  - closely check the way the `service` procedure is used. It takes the service type and a configuration like below. It is not valid to apply the type to the configuration.

(service oddmuse-service-type
  (oddmuse-configuration ...))

  - The configuration need not use `inherit` if you intend to take the defaults. The record type’s defaults will be used already when using the construction procedure. The configuration would look like this:

(oddmuse-configuration
  (root “blah”)
   ...)

Hope that helps.

- John
