[Bug 197219] Re: /usr/local/lib/python/sitecustomize.py broken due to overriding sitecustomize in /etc

[Thomas Güttler]

Ubuntu 18.04 does come with a sitecustomize.py file.

I think this is not a good solution.

I would really like to be able to execute some python code during
interpreter start.

AFAIK sitecustomize.py is the way to got. But if ubuntu provides one,
then this does not work.

Title:
  /usr/local/lib/python/sitecustomize.py broken due to overriding
  sitecustomize in /etc

Bug description:
  sitecustomize.py files have been added to /etc/python2.5/ nad
  /usr/lib/python2.5/ in hardy, which breaks the use of /usr/local/lib
  /site-python/sitecustomize.py, silently causing it to not be imported.

  My impression has always been that sitecustomize.py is to be reserved
  for the user (i.e., it's the python equivilent of debian's
  /usr/local/, thou shalt not touch it).

  site.py already allows for distribution specific additions; if they
  are to be placed outside site.py, then they should be placed in a
  third file such that the import of sitecustomize.py still proceeds as
  expected by the user.
