Yes, it is working like a charm. You live and learn.

But the creation of an init.d script is still worth implementing?

I'd suggest to make an option "Target filesystem options"->"Device
creation" and then
 "Target filesystem options"->"Device creation"->"static" and as
suboption "device table file"
 "Target filesystem options"->"Device creation"->"dynmic" and as
suboptions "udev" and "mdev"
 and then something with hotplugging
