I use guix because, while it has a small community, the packaging language is one of the easiest I've ever used.
Every distro I've tried I've always run into having to wait on packages or support from someone else. The package transformation scheme like what nixos has is great but Nixlang sucks ass. Being able to do all that in lisp is much preferred.
Plus I like shepherd much more than any of the other process 0's
You can use nix alongside guix, it'll just double-up the dependencies on disk:
Services are, in guix terms, any configuration change to a computer, so creating your own service 99% of the time is just extending
etc-service-type
and creating a variable interface to fill in the config file text yourselfCreating a service as in a daemon of some kind uses shepherd and involves extending
shepherd-service-type
orhome-shepherd-service-type
with your service description, depending on whether the service runs in root or user space.Shepherd service configurations aren't actually part of the guix spec(https://www.gnu.org/software/shepherd/manual/shepherd.html#Defining-Services), but still use Guile, so you can interoperate them super easily.
It's important in guix to understand lisp pretty thoroughly, and knowing how to program lisp is still a very useful skill to have so I'd recommend learning it even if you never touch guix.
