[Cooker] Formating partition

[Sylvain Vignaud]

In older Mandrake, ext2 partitions were formated with default option.
Should it still be the case, the formating options may be changed with
enabling Superblock and reducing the number of inode.

For exemple I have one 1Go partition formated during an installation,
and a 2Go partition reformated with the above options. Running
fsck.ext2) is FAR faster on the 2Go partition (10-20s maybe) than on the
1Go standard-formated partition.
