Right,

I think it should be this (minus the debug):

   for d in run log tmp lock; do
     echo ${D}
     echo $d
     ln -sfv ${localstatedir}/volatile/$d ${D}/$d
   done

Which gives:

DEBUG: Executing shell function do_install
/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image
run
'/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image/run' 
-> '/var/volatile/run'
/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image
log
'/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image/log'

/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image
tmp
'/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image/tmp/tmp' 
-> '/var/volatile/tmp'
/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image
lock
'/mnt/SSD/oe-r0005/r0005/tmp/work/beaglebone-oecore-linux-gnueabi/base-files/3.0.14-r73/image/lock'

The only issue I am having is still the double tmp/tmp thing; anyone 
know why it is doing it? It seems like a weird substitution or 
something.....
