What do you think? With the patch you submitted upstream (not the patches you attached to your previous email here), I can confirm the issue is fixed for me, and that I do NOT observe the errors you mentioned above. I see the patch was incorporated into Guix master in commit aa1f0896fb15a0bdcc5474839c8afdbb2520d603. That is good, and I think this issue can be resolved. If nobody follows up in a few days' time, let's close the bug report. Regarding your other patch in this thread to find the "ip" program at run-time, could you open a new bug report or patch (via guix-patches@gnu.org) for that? It seems unrelated to the issue at hand. Thank you for your help, -- Chris
