Hmm interesting!

If I follow correctly that's mean I have to create:

VIRTUAL-RUNTIME_wireless-daemon and then people can override it.

If the (R)DEPENDS on a recipe change depending on the wireless daemon that
was chosen(i.e. connman), do you handle it with d.getVar and
d.setVar("DEPENDS... inside a
anonymous python function inside the recipe?

The packageconfig would like this ?

PACKAGECONFIG[wifi] = "--enable-wifi, --disable-wifi,
${VIRTUAL-RUNTIME_wireless-daemon}, ${VIRTUAL-RUNTIME_wireless-daemon}"

Example:

if VIRTUAL-RUNTIME_wireless-daemon == "iwd":
    DEPENDS += "iwd"
    EXTRA_OECONF += "--enable-iwd"
elif VIRTUAL-RUNTIME_wireless-daemon == "wpa-supplicant":
    DEPENDS += "wpa-supplicant"


Thanks,
Max.
