It is the beginning of march. Since about the begining of the year my teacher and grad advisor have been solidfy the basic structure of the slack space filesytem. I originally based one the ext2 file system but in the end we decided to go with one that resembled a FAT system. Basically there are four main structures a 'superblock', a bitmap for which inodes have slack, a file allocation table establishing a slack block link-list, and a file table for cross-referencing a filename and its starting inode. This isn't the best structure for a filesystem, but like i said it is for simplicity.
