Very nice!

I think it’s worth considering, taking into account maintenance
considerations as Liliana wrote.

Normally, adding a service amounts to adding a line in the ‘services’
field:
(operating-system
;; …
(services (append (list (service nginx-service-type) …)
%base-services)))
It is more verbose that what you have, but it’s still roughly one line
(or one entry) per service.
Another interesting bit in your channel are templates though: an OS
template for hosting at OVH, etc. These are very valuable because they
take care of all the boilerplate.
Thanks for sharing!
