Loading a custom device tree overlay on Ubuntu

Ok… After getting my 1-Wire temperature sensor to work (see this post), I spent hours trying to get my custom 1-wire virtual cape at boot time using uEnv.txt :

But I always get this error :

Working great from command line after booting :

Seems to be a bug in the kernel : http://hipstercircuits.com/enable-device-tree-overlay-on-startup-on-beaglebone-black/

So, quick and dirty solution (I don’t wan’t / know how to build a custom kernel…) : so I added the command into /etc/rc.local

Now it is loaded at boot time !
