Then please keep your thoughts that do not match facts private.

The code you mentioned was gated by env['systemd'].  Maybe
instead "env['systemd'] and env['target']"?

Seriously?  Seems to me you are either buliding gpsd for the present
hot, or for a target host, but not both at the same time.  What is the
use case for that?

Still lost me.

Maybe, but it is existing practice.  If you look at the email archives
you will see many rants on the insanity of existing practice, but we
can't change it, only adapt to it.

You gotta have some way to separate out the stuff used by the host, from
stuff that is for the target.  There are other ways that scons also
uses.  Use what works for you.

So, instead of spending time bike shedding, do you have a real problem
here that needs solving?
