The ones missing seem to be the sources used to bootstrap GCC and Guile 
(there might be a couple of false positives in that list, because: I 
added these one by one to the list after "hello" by using the wildcard 
/gnu/store/*-$i.drv, until guix build inside the VM stopped indicating 
missing dependencies):


binutils-2.23.2.tar.xz
bison-3.0.4.tar.xz
gc-7.6.4.tar.gz
gcc-4.8.2.tar.xz
glibc-2.18.tar.xz
guile-2.0.9.tar.xz
gcc-4.9.4.tar.xz
gettext-0.19.8.1.tar.gz
gmp-6.1.2.tar.xz
guile-2.2.3.tar.xz
libatomic_ops-7.6.4.tar.gz
libffi-3.2.1.tar.gz
libtool-2.4.6.tar.xz
libunistring-0.9.9.tar.xz
m4-1.4.18.tar.xz
perl-5.26.1.tar.gz
pkg-config-0.29.2.tar.gz
static-binaries.tar.xz
texinfo-6.5.tar.xz
zlib-1.2.11.tar.gz

Note that when I run guix build --check hello inside a VM created from 
a minimal configuration, it tries to build much more than just hello 
(e.g. GCC, Guile, …), whereas if I run it on my Guix host, it simply 
rebuilds hello and nothing else.

Including sources in guix archive --export

[Georges Dupéron]

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
From https://gtpmirror.gnu.or/gnu/hello/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,
