I see. The following still applies though:

‘Also, it should be possible to update the certificate bundle
(e.g. if it turns out some root was or became evil or something,
or was compromised) quickly, without going through a world rebuild.
So dependencies on "nss-certs" should be avoided.’

So perhaps you could define a "nss-certs-for-tests" variable
(currently just pointing to nss-certs), and add "nss-certs-for-tests" to
#:disallowed-references to prevent "nss-certs-for-tests" being used at
run-time?

I don't quite see _why_ Julia needs certificates at build time though ...
Also, I wonder if this causes reproducibility issues --- if we try to rebuild
julia after, say, 50 years, e.g. by using "guix time-machine", wouldn't the
certificates become invalid, and would therefore the build of Julia fail?

Greetings,
Maxime.
