Out of curiosity: Where do you use gnURL in the system? For
normal user experience it was never intended (though it would
work). It would be nice to know if another project depends on it,
as we've started looking into wget2 as a successor to cURL for
GNUnet.

Not that we make it obsolete and people really use it. I have no
problem with long-term maintenance.

https://curl.haxx.se/docs/sslcerts.html what applies is this +
some grepping through the cURL source and reading it.

probably useful TIL of this whole issue: cURL could suffer the
same issue if we try this, and I need to test all the options.

That really is a cURL specific bug though. I wouldn't mind
extending gnURL where it makes sense, but due to the high speed
chase with cURL it is difficult.

... with the only problem that operating-system profile
activation does not exist (yet ;)?) for other systems, iirc.

Nope, they aren't. Hm. Curious.

Damn. I'll look into it as soon (or slow) as I can. Time is
limited atm.

Thanks for your reply so far. I'll also look into spinning up
some addition gitlab CI jobs to see if I can replicate what we
encountered.
We don't have GuixSD runners yet, but some people on our side are
working on it.

If you have more, like build logs etc would you like to send them
in here, open a bug on our (GNUnet) Mantis instance or send them
to the gnunet bugs list?

Thanks!
