The setup is obviously is cross test, built using buildroot. The system is minimal
with root allowed w/o password to enable tests to run quickly.

On host I do the following which certainly involves root.

| make test-wrapper='<path-to-build-folder>/scripts/cross-test-ssh.sh
root@192.168.0.20' xcheck

So guess it needs to be sshd or some other user on target ?
