control information.  It supports a range of protocols and over a dozen USB
devices.  It can run as a standalone service, which is useful for converting
signals between protocols, or alternatively using the OLA API, it can be used
as the backend for lighting control software.  OLA runs on many different
platforms including ARM, which makes it a perfect fit for low cost Ethernet to
DMX gateways.")

Reported by Attila Lendvai &lt;attila@lendvai.name&gt;.

Previously, if a narinfo was available but its corresponding nar was
missing (for instance because the narinfo was cached and the server
became unreachable in the meantime), 'guix substitute --substitute'
would try to download the nar from its preferred location and abort when
that fails.  This change forces one retry with each of the URLs.

* guix/scripts/substitute.scm (download-nar): Do not catch
'http-get-error?' exceptions.
(system-error?, network-error?, process-substitution/fallback): New
procedures.
(process-substitution): Call 'process-substitution/fallback' upon
'network-error?'.
