# Once again, Debian is weird. Package-installed Python is system-only, and does not
# play well with pip. See  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=765022#30
# and https://wiki.debian.org/Python#Deviations_from_upstream
#
# So we copy python from the Docker "Official Image" for python, (not to be confused with
# any official python image provided by python upstream). See https://hub.docker.com/_/python/ for details.
#
# Bad is the fact that python, being an interpreted language, installs a lot of shell scripts
# that specifically reference the location of the python interpreter or other things, those
# locations being baked in at install time. So it does not work to install python in `/dist`
# and then later copy `/dist` to `/usr/local`: The installed scripts would have `!#/dist/bin/python`
# baked in and fail. So the official image starts with a basically empty /usr/local/,
# installs python into /usr/local, and then we copy /usr/local over.
