No, it doesn't quite work that way.  You have to mount a particular
partition using a specific filesystem (i.e., ntfs, vfat, ext2, ext3,
ext4, etc.).  A partition formatted using ext2 can be mounted using
the ext2, ext3, or ext4 filesystem driver.  You can explicitly specify
what filesystem should be used to mount a particuar partition using
the -t option to the mount program, or by specifying a particular
filesystem type in the /etc/fstab file.
