There is a substitute on Berlin:

$ guix weather -s armhf-linux gst-plugins-good
computing 1 package derivations for armhf-linux...
looking for 1 store items on https://ci.guix.gnu.org...
updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
https://ci.guix.gnu.org
  100.0% substitutes available (1 out of 1)
  at least 4.1 MiB of nars (compressed)
  5.5 MiB on disk (uncompressed)
  1.402 seconds per request (1.4 seconds in total)
  0.7 requests per second

I'm not sure to what extent we should patch packages to work with QEMU
transparent emulation.  And currently the CI does not use it at all for
32-bit ARM (albeit for rather different reasons).

Thoughts?

Yes.

Do we have reasons to believe the QEMU user-mode emulation is not
reliable/accurate?  That'd be a bummer.  I haven't seen any disclaimer
in QEMU's documentation ?

Thanks,

This was tested in QEMU (unreliable) and on an older version of (1.16.2,
now at 1.18.5).

Closing.
