[oe] [PATCH] image.bbclass: create /etc/device_table from IMAGE_DEVICE_TABLES

[Antonio Ospite]

Right now when the 'devices' script from initscripts is called the
layout specified in IMAGE_DEVICES_TABLES is lost.

With this change the default behaviour when no IMAGE_DEVICE_TABLES is
specified is to always use files/device_table-minimal.txt

Hi Koen et al.,

This looks to be enough in my preliminary tests.
As for the default behaviour change, I guess it is acceptable and
files/device_table-minimal.txt can always be changed in a later commit, maybe
to resemble more the very /etc/device_table from initscripts.

This patch fixes http://bugs.openembedded.org/show_bug.cgi?id=3593 and I
consider it an orthogonal problem to having static /dev, so this can be
reviewed alone.

Note that I used /etc instead of ${sysconfdir} on purpose as /etc is already
hardcoded in several places in image.bbclass.

Thanks,
   Antonio Ospite
