Hi!

Is it possible to export a .nar including the sources necessary to rebuild that package?

I tried running these commands on the host:

sudo guix archive --generate-key

guix archive --export --recursive hello > hello.nar

And these commands inside a fresh, minimal GUIX environment without network access:

guix archive --authorize < signing-key.pub

guix archive --import < hello.nar

$(guix build hello)/bin/hello # works

guix build --check hello # fails

The above fails because it tries to download the sources:

Starting download of /gnu/store/…-hello-2.10.tar.gz

In procedure getaddringo: Name or service not known

I have created at https://github.com/jsmaniac/guix-reproducible-system/tree/guix-question a small automated environment which creates the archive, creates a QEMU VM with a minimalistic Guix configuration, copies the .nar archive inside the VM and tries the commands above.

Thanks,

Georges Dupéron
