I think but am not 100% sure this has introduced another regression:

https://autobuilder.yoctoproject.org/main/builders/nightly-oecore/builds/177

The issue is that X doesn't start in oe-core built images. It does work
correctly in poky. The issue is that the /etc/init.d/xserver-nodm script
returns:

root@qemuarm:/etc# /etc/init.d/xserver-nodm start
Starting Xserver
su: applet not found

or to be more specific:

root@qemuarm:/etc# su -l -c '/etc/X11/Xserver&' xuser
su: applet not found


The poky images appear to work since we install bash. If you remove bash
from packagegroup-core-device-devel.bb, the poky images will show the
same error.

I think this is something to do with the none-suid busybox binary not
containing su support, but why su is being called there, I don't know.
su is being provided by shadow in the image. If I make su provided by
busybox the problem also goes away.

Cheers,

Richard
