Hi,

Yes.  I’m surprised we didn’t hit a problem before, despite having
thousands of Python packages.  Can we work around it for the one package
that hits that bug?  (Until a fix like you propose lands.)

If you can use @@ to get at ‘ensure-no-mtimes-pre-1980’, I’d still
suggest to do that for ‘criu’.

Does that make sense?  Or am I overlooking something?

Thanks,
