I've been thinking... shouldn't this be in a chromeos specific overlay?

[Noel Gordon, 2017/02/27 02:58:08]

Nope.  Mojo does not have per-os overlays.

And with my mojo developers hat on, I don't think we should add them (nor
per-build-flag overlays either).  Overlays are a developer paint pain, so the
fewer of them, the better imho.

There might be some benefit to your suggestion, which I might be overlooking,
but this is not the right forum to address it ... perhaps send mail to the mojo
list instead.
