| 7 | Ext2 is a standard Linux file system for hard disks. |
| 8 | |
| 9 | This filesystem driver is deprecated because it does not properly |
| 10 | support inode time stamps beyond 03:14:07 UTC on 19 January 2038. |
| 11 | |
| 12 | Ext2 users are advised to use ext4 driver to access their filesystem. |
| 13 | The driver is fully compatible, supports filesystems without journal |
| 14 | or extents, and also supports larger time stamps if the filesystem |
| 15 | is created with at least 256 byte inodes. |
| 16 | |
| 17 | This code is kept as a simple reference for filesystem developers. |

| 25 | Extended attributes are name:value pairs associated with inodes by |

| 35 | Posix Access Control Lists (ACLs) support permissions for users and |

| 44 | Security labels support alternative access control models |
| 45 | implemented by security modules like SELinux. This option |
| 46 | enables an extended attribute handler for file security |
| 47 | labels in the ext2 filesystem. |
| 48 | |
| 49 | If you are not using a security module that requires using |
| 50 | extended attributes for file security labels, say N. |
