Adding mdevd to the s6 boot process

Hi again,

Having got s6-linux-init and s6-rc to handle the ( early stage) boot
process, I decided, perhaps foolishly, to add mdevd to the mix.

Mdevd now warns 'unable to spawn ./run' every 60 seconds.

Any hints as to what ./run it is trying to run and where it should be?

Thanks
