Does anyone know why or when you might choose another option besides "typical"?? (options such as news, largefile, largefile4 etc)

or the pratical example situations where options such as news, largefile, largefile4 etc are used ?

The options give different settings for things like inode ratios, blocksize, etc.

If you have a filesystem that will only contain large files, such as iso images, etc,
then you don't need as many inodes, so you'd use a higher bytes to inodes ration.

See man mke2fs.conf, the contents of /etc/mke2fs.conf, and man mkfs.ext2 for details.

Don't agonize over it too much. When I look at a 10GB ext3 file system built
with default parameters (4KB block size, one inode for every 4 blocks), the
inodes are using just 1.5% of the total space. About the only time to be
concerned at all is if you know that the file system will be used almost
exclusively for tiny files and you would want more inodes.
