   8           Ext2 is a standard Linux file system for hard disks.

  10           This filesystem driver is deprecated because it does not properly
  11           support inode time stamps beyond 03:14:07 UTC on 19 January 2038.
  12
  13           Ext2 users are advised to use ext4 driver to access their filesystem.
  14           The driver is fully compatible, supports filesystems without journal
  15           or extents, and also supports larger time stamps if the filesystem
  16           is created with at least 256 byte inodes.

  26           Extended attributes are name:value pairs associated with inodes by
  27           the kernel or by users (see the attr(5) manual page for details).

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

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