Building the artifact in Buildroot:

```auto
$ make
...
buildroot/output/host/usr/bin/mender-artifact write rootfs-image --file buildroot/output/images/rootfs.ext4 --output-path buildroot/output/images/foo-rootfs.mender --artifact-name foo-rootfs --device-type foo

$ buildroot/output/host/usr/bin/mender-artifact --version
mender-artifact version 3.8.0

```

Attempting to install the artifact on the target:

```auto
# mender install ./foo-rootfs.mender 
INFO[0000] Loaded configuration file: /etc/mender/mender.conf 
INFO[0000] Mender running on partition: /dev/mmcblk0p2

# mender --version

```

Note that when I upload the `rootfs.ext4` directly to [hosted.mender.io](http://hosted.mender.io), which should generate a Mender artifact, I do not have this issue. Instead I run into the following:

I downloaded the pre-built `mender-artifact` version 3.9 and built a new artifact. That artifact installed successfully on the target.

I bumped the version in Buildroot from 3.8.0 to 3.9.0 and it appears to also work successfully.
