Then maybe rlaager can provide a summary of the 4 different cases:
A. distro install: /etc, /bin, etc.
B. system install: /usr/local/etc, /usr/local/etc, etc.
C. user install: ~/etc, ~/etc, etc. or similar
D. packager install: /tmp/etc, /tmp/bin, going into a package
And, most important, in some systems, all FOUR must be able to

Yup. Because we really need 4 totally different solutions, people
keep trying to get to 1.
No otehr projects seem to have this loop issue...

Only for B. and C. No other packages seem to need to violate the FHS.
I agree PYTHONPATH is the standard solution used by all.

Uh, lost me. What old system? NTPsec has been using PYTHONPATH just

Once again, only usefull for SOME cases of B. and C. Violates the
FHS. Breaks many use cases where A., B., C., and/or D. co-exist.

I've not looked at the code. Care to elaborate?

Taht is a given. :-)

Do not conflate two different issues:
1. where and how to install
2. host to get waf to do 1.
I have taken no position on #2 as we have not agree on #1.
No point thinking about how to do #2 until #1 is agreed.
Is it more helpfuil if I mention that gpsd has no issues with A., B., C.,
and D. gpsd does the totally standard python install thing, just like
ntpsec needs to.

Well then, that needs to be done. If we can't agree on the summary then
the 615 code can't be merged.
