Somehow it works just fine in my `home-manager` configuration, I assume it is
using the system `nixpkgs` and its `lib` attribute that I extended. Whereas the
NixOS system must be injected with the extended one intentionally.
Inspired by this [1] repo, I want to add some functions to `lib.my`. I
would have liked to make it work without having to use an overlay, but I
did not manage to do it...

I have separated the modules into host-specific settings, and generic
settings that ought to be shared by every host.
I only have the 'porthos' host for now, but intend to also add my laptop
'aramis' at some point to this repository.
