For clarity, I’d write the list: @code{'(wpa-supplicant)}.

To preserve backward compatibility and to provide a reasonable default
(with working WiFi), I think the default for ‘shepherd-requirement’
should be '(wpa-supplicant) rather than the empty list.

(BTW, it seems that wpa-supplicant can be DBus-activated, maybe that’s
what we should do instead?  But let’s forget about it for this patch
series.)

Thanks,
Ludo’.
