- * Description:
- * Make a FAT file system image on the specified block device

- * fmt - Describes characteristics of the desired filesystem
- *
- * Return:
- * Zero (OK) on success; -1 (ERROR) on failure with errno set appropriately:
- *
- * EINVAL - NULL block driver string, bad number of FATS in 'fmt', bad FAT

- * ENOENT - 'pathname' does not refer to anything in the filesystem.
- * ENOTBLK - 'pathname' does not refer to a block driver
- * EACCES - block driver does not support wrie or geometry methods
- *
- * Assumptions:
- * - The caller must assure that the block driver is not mounted and not in
- * use when this function is called. The result of formatting a mounted
- * device is indeterminate (but likely not good).
