criu fails like this for me:
copying crit.egg-info/top_level.txt -> build/bdist.linux-x86_64/egg/EGG-INFO
zip_safe flag not set; analyzing archive contents...
pycriu.images.__pycache__.__init__.cpython-310: module references __file__
creating dist
creating 'dist/crit-3.17.1-py3.10.egg' and adding
'build/bdist.linux-x86_64/egg' to it

ValueError: ZIP does not support timestamps before 1980
I came across this:
https://docs.python.org/3/library/zipfile.html#zipfile-objects
So apparently when creating a zipfile object (this is the constructor
we are looking at, right?), one can pass a parameter that tells it to
not bother about time stamps of old files.
Then it is a matter of finding out where it happens. I think it is
line 450 of (in my case)
/gnu/store/dy3xh053ahkhrp2jamggq8cpsyvp8mg0-python-3.10.7/lib/python3.10/site-packages/setuptools/command/bdist_egg.py
which reads
z = zipfile.ZipFile(zip_filename, mode, compression=compression)
Maybe we should patch our Python so that it becomes
z = zipfile.ZipFile(zip_filename, mode, compression=compression,
strict_timestamps=False)
?
(not before the core-updates merge, however)
But is a bit surprising that it does not happen all the time;
or are only a few packages calling bdist_egg.py?
