now that I've had dinner and time to reflect upon this...
I understand that scp / sftp 'permit' the user to influence the owner,
group, all permissions but the one thing that I have learned to love
about Linux - which I have to presume comes from UNIX (since I am quite
unlearned on UNIX) is that the settings do not come from nowhere and the
answer that I received from my parents when I was a child...just because
doesn't apply here.
So I am left to wonder, where do these settings come from? Normally the
umask settings for any user come from the users shell settings and
failing anything in the user's profile, from the system profile. I
suppose that it's possible that the umask settings are derived from the
source code and compiled as a default and since I didn't peruse the
source code, I wouldn't know that. Perhaps this is a good time to
install the openssh source for clues.
One thing seems certain to me, that when I simply transfer files via
scp, the default, uninfluenced privileges assigned to any files and
folders have to come from somewhere.
