atomic_write
When I use :file_store, Rails application must have permission to write in 'public/' directory. If it doesn't have access to 'public/', cache files are created as temporary files - i.e. 'menu.cache.20222.0' instead of 'menu.cache'.
atomic_write creates (in some cases) a file /permissions_check.XXXXXXX to determine the default permissions. This file is created in the current directory. If the script hasn't permission to write in the current directory, it fails and the code, which renames temporary file (created by the atomic_write) and changes its permissions, isn't executed.
The file .permission_check should be created in the same directory as the output file.
Note: It's my first report. If something is missing, let me know, I will add it.

Looks like this fix was already applied.
