I really prefer a 'good default' with reproducible results.
Advanced users can always call check-package directly.

But perhaps some developer can hit some corporate policies when developing
patches inside the company:
- can't run docker at all
- can't download docker images from the internet
For that poor souls, I will withdraw this patch and resend. :)

Well... we could instead change de manual to say:

299 ---------------------
300 $ utils/docker-run make check-package
301 ---------------------

CI builds already run inside the same docker image, so no change there.

I was trying to accomplish with this series, among other things, a way to
ensure the same results locally when compared to CI builds.

One interesting reproducibility issue that is already taken into account by this
series, even outside the docker image:
patch 14
file utils/check-package
line 98

I developed outside the docker image and when I run on CI build the python files
were being not tested and ignored by check-package.
See the reason:

$ utils/docker-run python3 -c \
  "import magic;" \
  "print(magic.from_file('utils/brmake', mime=True));" \
  "print(magic.from_file('utils/check-package', mime=True))"; 
text/x-shellscript
text/x-script.python

$ python3 -c \
  "import magic;" \
  "print(magic.from_file('utils/brmake', mime=True));" \
  "print(magic.from_file('utils/check-package', mime=True))"; 
text/x-shellscript
text/x-python

But as I say above, I will withdraw this patch and resend the series.


Regards,
Ricardo
