а ещё уже для самой DavFS delay_upload — сколько секунд ждать после записи файла в директорию.
When a file that has been changed is closed, mount.davfs will wait that many seconds before it will upload it to the server. This will avoid uploading of temporary files that will be removed immediately after closing. If you need the files to appear on the server immediately after closing, set this option to 0.
Default: 10
