Hi,
I hope you found the solution in the meantime, but in case it helps, there's
also an issue in your service-extension that will indeed cause 'Wrong type to
apply' or 'Wrong type argument' errors when you try to build your system.
The second argument of service-extension should be a function that takes one
argument (the configuration passed to openslides-service-type) and returns a
valid configuration for shepherd-root-service-type, which I assume is a list of
shepherd services (I only tried with home-shepherd-service-type).
Since you don't need a configuration, you can use 'const' to transform the
constant list of services into a function. So something like this should work:
--8<---------------cut here---------------start------------->8---
(define-public openslides-service-type
(service-type
(name 'openslides)
(description "The openslides-service-type")
(extensions
(list (service-extension shepherd-root-service-type
(const (list openslides-shepherd-service)))))
(default-value '())))
--8<---------------cut here---------------end--------------->8---
