Hi all,
I've been using NixOS for a few years and now I want to try out Guix.
The goal is to see whether there is a benefit to using both and what we can
learn from each other.

I’ve come to the conclusion that it’s not a worthy goal, as in, it would
cost more than it’s worth. guix-daemon is already incompatible with
nix-daemon on a few things, such as the “builtin:download” derivation
builder.
But the Guix manual at 2.2 [1] says:
When a working installation of the Nix package manager is available, you can
instead configure Guix with --disable-daemon. In that case, Nix replaces the
three dependencies above.
Guix is compatible with Nix, so it is possible to share the same store between
both. To do so, you must pass configure not only the same --with-store-dir
value, but also the same --localstatedir value. The latter is essential because
it specifies where the database that stores metadata about the store is
located, among other things. The default values for Nix are
--with-store-dir=/nix/store and --localstatedir=/nix/var. Note that
--disable-daemon is not required if your goal is to share the store with Nix.
How much of that is still true? The daemon is not compatible anymore and
I don't think it is a good idea to have two different daemons share the same
store.
Is there still the a possibility to use either Nix on GuixSD or Guix on NixOS
without duplicating the store or running two daemons?
Or e.g. use Nix with Guile?
Cheers,
Daniel
