When running mke2fs, if a file system is detected
on the device, we use Undo I/O manager as the io manager.
This helps in reverting the changes made to the filesystem
in case we wrongly selected the device.
The environment variable MKE2FS_SCRATCH_DIR
is used to indicate the directory within which
With the new mke2fs changes the output of the
command differs if we run mke2fs on a device that
already have the file system. So erase the file system
before running mke2fs so that output remain as expected.

Add new option -I to tune2fs.
This is used to change the inode size. The size

As a part of increasing the inode size we increase the
