Linux Ext2 filesystem

Where driver is one of the devb-* drivers.
The Ext2 filesystem (fs-ext2.so) provides transparent access to Linux disk partitions. This implementation supports the standard set of features found in Ext2 versions 0 and 1.
Sparse file support is included in order to be compatible with existing Linux partitions. Other filesystems can only be "stacked" read-only on top of sparse files. There are no such restrictions on normal files.
If an Ext2 filesystem isn't unmounted properly, a filesystem checker is usually responsible for cleaning up the next time the filesystem is mounted. Although the fs-ext2.so module is equipped to perform a quick test, it automatically mounts the filesystem as read-only if it detects any significant problems (which should be fixed using a filesystem checker).
The following features are not currently supported:
Although Ext2 is the main filesystem for Linux systems, we don't recommend using fs-ext2.so as a replacement for the QNX 4 filesystem (fs-qnx4.so). Currently, we don't support booting from Ext2 partitions. Also, the Ext2 filesystem relies heavily on its filesystem checker to maintain integrity; this and other support utilities (e.g. mke2fs) are not currently available for QNX Neutrino.
