75 This is the journaling version of the Second extended file system
76 (often called ext3), the de facto standard Linux file system
77 (method to organize files on a storage device) for hard disks.
78
79 The journaling code included in this driver means you do not have
80 to run e2fsck (file system checker) on your file systems after a
81 crash. The journal keeps track of any changes that were being made
82 at the time the system crashed, and can ensure that your file system
83 is consistent without the need for a lengthy check.
84
85 Other than adding the journal to the file system, the on-disk format
86 of ext3 is identical to ext2. It is possible to freely switch
87 between using the ext3 driver and the ext2 driver, as long as the
88 file system has been cleanly unmounted, or e2fsck is run on the file
89 system.
90
91 To add a journal on an existing ext2 file system or change the
92 behavior of ext3 file systems, you can use the tune2fs utility ("man
93 tune2fs"). To modify attributes of files and directories on ext3
94 file systems, use chattr ("man chattr"). You need to be using
95 e2fsprogs version 1.20 or later in order to create ext3 journals
96 (available at <http://sourceforge.net/projects/e2fsprogs/>).

1500 If you want your Linux box to act as an NFS *server*, so that other
1501 computers on your local network which support NFS can access certain
1502 directories on your box transparently, you have two options: you can
1503 use the self-contained user space program nfsd, in which case you
1504 should say N here, or you can say Y and use the kernel based NFS
1505 server. The advantage of the kernel based solution is that it is
1506 faster.
1507
1508 In either case, you will need support software; the respective
1509 locations are given in the file <file:Documentation/Changes> in the
1510 NFS section.

1512 If you say Y here, you will get support for version 2 of the NFS
1513 protocol (NFSv2). If you also want NFSv3, say Y to the next question
