Hi Florian,

(+Cc: Mathieu, who’s probably more familiar with Connman.)

"pelzflorian (Florian Pelz)" <pelzflorian <at> pelzflorian.de> skribis:

I don’t think so, because currently shepherd opens #:log-file in append
mode.  So I believe everything is there.

Nothing caught my eye in the log (but there’s a lot of stuff in there),
except (but I don’t know if it’s relevant):

  229: 0x7f98cd08d400: 1586778311.080442 [connection.c(2626):bus_transaction_send_error_reply] Sending error reply org.freedesktop.DBus.Error.ServiceUnknown "The name net.connman was not provided by any .service files"

And indeed, there’s no ‘.service’ file for that:

--8<---------------cut here---------------start------------->8---
$ find $(guix build connman) -name \*.service
/gnu/store/vclzrvbxac8ipc8g1ncq5gjjj8gdvxw3-connman-1.38/share/dbus-1/system-services/net.connman.vpn.service
--8<---------------cut here---------------end--------------->8---

The attach patch changes connman so that ‘net.connman.service’ is
installed.

Does it make any difference?

Thanks,
Ludo’.
