[New-bugs-announce] [issue24231] os.makedirs('/', exist_ok=True) fails on Darwin

[Matthew Wedgwood]

New submission from Matthew Wedgwood:

On Darwin, os.mkdir('/') raises IsADirectory. On Linux, the same call raises FileExistsError. The implementation for os.makedirs() in Python 3.2+ checks only for the latter when evaluating the exists_ok parameter. This causes os.makedirs('/', exist_ok=True) to fail on Darwin but succeed on Linux.
