Subject: 'guix system' failure due to substitute being temporarily 404 ->
 Implement a retry attempts?
Date: Thu, 30 Jun 2022 08:19:38 +0000

[Message part 1 (text/plain, inline)]

Seems that the substitute server went down just as i was doing `guix 
system reconfigure /path/to/config.scm` which produced a failure thus 
proposing to implement a retry attempts to make this process more 
reliable in mission critical environment

While retrying and potentially falling back to local builds would be
nice improvements to user experience, I seriously hope your mission-
critical software does not assume reliability of anything network-
related.  As a matter of fact, Guix already provides the only guarantee
any system can have under this circumstance: that your device won't be
bricked when failing to download something from the internet.

Cheers

I get this error pulling from the official Guix servers.
