   4          Ext2 is a standard Linux file system for hard disks.
   6          To compile this file system support as a module, choose M here: the
   7          module will be called ext2.
   9          If unsure, say Y.

  14        help
  15          Extended attributes are name:value pairs associated with inodes by
  16          the kernel or by users (see the attr(5) manual page, or visit
  17          <> for details).
  19          If unsure, say N.

  26          Posix Access Control Lists (ACLs) support permissions for users and
  27          groups beyond the owner/group/world scheme.

  37        help
  38          Security labels support alternative access control models
  39          implemented by security modules like SELinux.  This option
  40          enables an extended attribute handler for file security
  41          labels in the ext2 filesystem.
  43          If you are not using a security module that requires using
  44          extended attributes for file security labels, say N.

  50          Execute in place can be used on memory-backed block devices. If you
  51          enable this option, you can select to mount block devices which are
  52          capable of this feature without using the page cache.
  54          If you do not use a block device that is capable of using this,
  55          or if unsure, say N.
