…y filesystems (pythonGH-155827) The "forkserver" start method (the default start method on non-Windows systems) requires the ability to write temporary files, which is not possible if TMPDIR is read-only (e.g., k8s containers mounted with `readOnlyRootFilesystem=True`). On such filesystems, the default start method changes from "forkserver" to "spawn".

The "forkserver" start method (the default start method on non-Windows systems)
requires the ability to write temporary files, which is not possible if TMPDIR
is read-only (e.g., k8s containers mounted with
readOnlyRootFilesystem=True).On such filesystems, the default start method changes from "forkserver" to "spawn".
