Sorry I probably mislead you regarding this.

The Mender client will use the /var/lib/mender path, that is pretty
much hard-coded. The fact that it was a link to /data is simply to
provide a "valid" path, because the mender.service will create the
directory structure on start-up. The reason it is a link is because
you can change it to point to where ever your persistent storage is.

So we either have to have a "mkdir -p /var/lib/mender" in mender.mk or
use the link that this patch provides.

Sorry once again for not making this clear.

Will do.
