From: Mark Asselstine <mark.asselstine@windriver.com>

The existence of a /etc/hostname file causes any hostname provided on
the kernel command line or via dhcp to be overwritten by the
initscripts 'init.d/hostname.sh'. This change allows you to set a
value of "" for 'hostname' which will skip the creation of the
/etc/hostname file by the base-files package.

Is this missing a hostname ??= "openembedded" perhaps?

Cheers,

There is already a hostname = "openembedded" in the package.  Nothing in that 
part was changed by this patch.  The normal override process is to define 
hostname_override = "newhostname".

I verified this is working properly.
