This node specifies the filesystem type of the device or partition. Many different filesystems are supported but we'll take a look at the most common ones only.<br><br>
<b>ext2</b> and <b>ext3</b> Very likely your Linux partitions are Ext3. Ext2 used to be the standard filesystem for Linux, but these days, Ext3 and ReiserFS are usually the default filesystems for almost every new Linux distro. Ext3 is a newer filesystem type that differs from Ext2 in that it's journaled, meaning that if you turn the computer off without properly shutting down, you shouldn't lose any data and your system shouldn't spend ages doing filesystem checks the next time you boot up.<br><br>
<b>reiserfs</b> Your Linux partitions may very well be formatted as ReiserFS. Like Ext3, ReiserFS is a journaled filesystem, but it's much more advanced than Ext3. Many Linux distros (including SuSE) have started using ReiserFS as their default filesystem for Linux partitions.<br><br>
<b>swap</b> The filesystem name is self-explanatory. The filesystem type "swap" is used in your swap partitions.<br><br>
<b>vfat</b> and <b>ntfs</b> Your USB stick is most likely formatted as Vfat (more widely known as FAT32). Your Windows partitions are probably either Vfat or NTFS. The 9x series (95, 98, ME) all use Vfat, and the NT series (NT, 2000, XP, Vista, 7) use NTFS but they may be formatted as Vfat, too.<br><br>
<b>auto</b> No, this isn't a filesystem type :-) The option "auto" simply means that the filesystem type is detected automatically. Sometimes the floppy and CD-ROM both have "auto" as their filesystem type. Why? Their filesystem type may vary. One floppy might be formatted for Windows and the other for Linux's Ext2. That's why it's wise to let the system automatically detect the filesystem type of media such as floppies and cdroms.
