cleaning the store

I erased ALL the prevoius generations and still there are some elements
that "guix gc -d ..." cannot eliminate from the store because they turn out
to be "still alive"

Of course emacs-cider is not installed in the current generation

I don't understand.

Is there a way to let guix tell me what is still pointing to those ?

They are referred to by a profile. You can see the full list of your
user's profiles with `guix package --list-generations`. Other users will
have their own profiles.

You can learn more about how to work with these profiles with `guix
package --help` and also in the manual, 3.2 Invoking guix package.

Thank you

There are only 2 profiles on this machine: mine and root's profile

As for mine, I eliminated ALL previous generations and emacs-cider is not
installed in the current one

As for root's profile:

$ guix package -p root --list-installed

returns nothing


and
$ guix package -p root --list-generations
guix package: error: profile 'root' does not exist


So which profile is pointing to those things ?

I think the argument to '-p' is the generation of the profile (an
integer). You should try running it as root, since I doubt you can read
root's profiles as an unprivileged user.

Also, consider that what you see in `guix package --list-installed` are
the top-level packages, but not their dependents. This package may be
a dependent of some package you've installed in your profile.

No, “--profile” or “-p” expects a *path* to a profile.  For root’s
profile you would either be root and use the default (no “-p” option),
or use “-p /root/.guix-profile” or similar, provided you have read
access to this file.

'guix gc' will tell you this.

    guix gc --referrers /gnu/store/...-cider-x.y.z

`guix package -s cider` returns nothing. Nor is that string present in
the Guix source tree. It's a private package, yes?

yes, it's a private package

I was trying to make a recipe for cider but there were some errors in the
log, some dependencies couldn't be reached.

Maybe I messed up the inputs.

I wanted to clean to be sure that there were o interferences from the relics

Now, 2 profiles show up among the referrers

But I can't find a single scrap belonging to cider in any generation

Now I should figure out who owns those profiles.

We'll see

Thanks for your help. Particulary for the --referrers switch. I had missed
that

If you make a change to your cider recipe, then the "relics" can't
interfere with later builds, because the new cider directory in
/gnu/store will have a new hash. It is impossible for the build process
to guess the hash of the old cider "relics", so they won't be used.

If you don't change the cider recipe, then the relics will be used.

Because I tried several variations of the recipe and got always the same
error, I thought something wrong was happening.

Now I notice that at least one of the unreachable dependencies is not well
packaged.

I guess I was a bit confused, sorry
