This allows write of files from the host filesystem in sandbox. There is currently no concept of overwriting the file and removing its existing contents - all writing is done on top of what is there. This means that writing 10 bytes to the start of a 1KB file will only update those 10 bytes, not truncate the file to 10 byte slong. If the file does not exist it is created.
