Bug#1099038: Acknowledgement (silx: Permission denied: '/usr/lib/python3/dist-packages/silx/pytest-cache-files-0lxt05lh')

[picca]

It seems that the pytest cache directory try to write under a read only 
part of the system...

Testing with python3.13:
============================= test session starts

platform linux -- Python 3.13.2, pytest-8.3.4, pluggy-1.5.0 --

rootdir: /usr/lib/python3/dist-packages/silx
plugins: typeguard-4.4.2, xvfb-3.0.0, mock-3.14.0
collecting ... collected 2523 items
The rootdir seems suspicious to me...
