I usually leave things more than a day before sending a ping email,
people can be busy but usually you'll get replies within a couple of
days on this list.

The postinst is executed by the package manager when the package is
installed. If that installation takes place during do_rootfs, ${D}
will refer to the rootfs directory for the image being built and ${S}
will probably refer to something else to do with the image recipe but
I'm not entirely sure on the details. If the installation takes place
on the device, or the postinst is delayed until the first boot, ${D}
and ${S} will not be set.

Hope this helps,
