A new question:
Why do we use /usr/bin/xterm here by hardcode? 
Can we change it to matchbox-terminal? Or, can we use some kind of
algorithm to determine the available terminal?

I asked the question because in the self-hosted-image of poky,
we don't have xterm (poky doesn't have a recipe for xterm) and I
think it may not deserve the effort to add a recipe for xterm only
for this specific usage in self-hosted-image.
