I just did a build, with the following defconfig:

BR2_arm=y
BR2_cortex_a8=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_LINARO_ARM=y
BR2_INIT_SYSTEMD=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_WPA_SUPPLICANT=y
BR2_PACKAGE_WPA_SUPPLICANT_DBUS_OLD=y
BR2_PACKAGE_WPA_SUPPLICANT_DBUS_NEW=y
# BR2_TARGET_ROOTFS_TAR is not set

So, it has systemd enabled and both the old and new dbus interfaces in
wpa-supplicant. And the BusName is definitely not empty:

$ cat lib/systemd/system/wpa_supplicant.service 
[Unit]
Description=WPA supplicant
Before=network.target
Wants=network.target

[Service]
Type=dbus
BusName=fi.w1.wpa_supplicant1
ExecStart=/usr/sbin/wpa_supplicant -u

[Install]
WantedBy=multi-user.target
Alias=dbus-fi.w1.wpa_supplicant1.service

Since we haven't heard from the original submitter since February, I'll
mark this patch as Rejected in patchwork.

Best regards,

Thomas
