File permissions
----------------
Permissions on build artifacts may vary, for example due to differing `umask` settings. The resulting permission differences may be reflected when archive files containing them are created.
When possible, it is preferable to create build artifacts using deterministic permissions so that variance does not arise. However, sometimes it may be easier or more practical to configure static permissions later in the build, when the archive files are created.
To configure file permissions when creating a `tar` archive, you can use the `--mode` argument. For example, to request that, by default, unpacked files should be readable by everyone by default, writable only by their owner, and to allow everyone to list directory/folder contents, add: `--mode=a=rX,u+w`
