Package: iwd Version: 1.14-3 Severity: normal X-Debbugs-Cc: and...@lists.savchenko.net
Dear Maintainer, iwd throws warning in the kernel ring buffer unless its start is delayed with `ExecStartPre=ip link set wlan0 up` in `iwd.service` unit. With the line above the warning is gone, however iwd can't be stopped/started after the boot. `systemctl restart` works though.
