[yocto] replace etc/network/interfaces with symbolic link

[Aurele Traynard]

many thanks for your concern, I finaly found my issue... there was no error.
I'm using a new distro since friday, this resulted in a new "tmp-glibc"
directory instead of my old "tmp" directory created by poky... I was
looking in the wrong directory. As you said in your first point I should
check the creation date!.


thanks
Aurèle

> be named something like run.do_install.15612.  If there are multiple in the

> incorrectly.
