File names have the following format: [ size: ] path [ free% [ max size ] : ] path If no size is specified, the files must exist and the contents will be overwritten if testing write or writea system calls. If a size is supplied, an attempt to create/grow/shrink path to the desired size will be made. size is an integer which defaults to bytes, but may be suffixed by 'b', 'k', or 'm' for blocks (4096 byte units), kilobytes (1024 byte units), or megabytes (2^20 byte units). If the size is a percentage, df is used to find how much free space there is (in blocks), and uses that. The maximum size is implied to be in blocks.
