Hi,

Users might want to ignore /etc/ssl/certs altogether and instead only
use their own set of certificates, so I’m rather reluctant to such a
change.

Now, I agree that there’s a usability problem: we don’t want every
Octave user to stumble upon a certificate error message.  I can think of
several solutions:

  1. We could add CURLOPT_CAPATH to the ‘native-search-paths’ of ‘curl’,
     assuming that variable is honored by libcurl itself.  It won’t
     solve this immediate issue, but it sounds like “the right way.”

  2. On GuixSD, we could define CURLOPT_CAPATH=/etc/ssl/certs in
     /etc/profile, like we already do for other variables.

  3. We could document this variable under “X.509 Certificates” in the
     manual.

#1 would have to go to ‘core-updates’.  WDYT?

Thanks,
Ludo’.
