File systems are defined in the kernel. The kernel supports many file systems, but they need to be compiled
in, or compiled as a module. When you compile a file system in the kernel, all you need to do is use mount
with the -t option and the right file system type.
If you have compiled a driver for a file system as a module, then you need to load the module first.
Here are a few of the available file systems:
·  msdos: This is the FAT file system used by DOS.
·  vfat: This is the FAT32 file system used by Windows 95 and Windows 98.
·  ext2: This is the default Linux file system.
·  iso9660: This is the default CD-ROM format.
