Looking at the file system and configuration, it seems that this is unlikely. >> I'm going to try and make some time to see if I can get this system back >> working again.

I don't have the right cables to attempt to get a serial connection to see what is going on in the early boot, so I tried running guix system init from some GuixSD installation media. I'm glad to say that it worked :) After running guix system init, I had a working system generation to boot with. I'll try to setup some kind of serial connection, so that I can attempt to debug further if this happens again. Thanks, Chris signature.asc Description: OpenPGP digital signature

What networking service do you use: wicd, dhcp-client-service, something else? Thanks, Ludo’.

What does /var/log/shepherd.log contain around that time? There’s an open bug that might be the culprit: https://bugs.gnu.org/23697 HTH, Ludo’.
