Saying Y here will allow you to use a regular file as a block
device; you can then create a file system on that block device and
mount it just as you would mount other block devices such as hard
drive partitions, CD-ROM drives or floppy drives. The loop devices
are block special device files with major number 7 and typically
called /dev/loop0, /dev/loop1 etc.
This is useful if you want to check an ISO 9660 file system before
burning the CD, or if you want to use floppy images without first
writing them to floppy. Furthermore, some Linux distributions avoid
the need for a dedicated Linux partition by keeping their complete
root file system inside a DOS FAT file using this loop device
driver.
To use the loop device, you need the losetup utility, found in the
util-linux package, see
<ftp://ftp.kernel.org/pub/linux/utils/util-linux/>.
The loop device driver can also be used to "hide" a file system in
a disk partition, floppy, or regular file, either using encryption
(scrambling the data) or steganography (hiding the data in the low
bits of, say, a sound file). This is also safe if the file resides
on a remote file server.
There are several ways of encrypting disks. Some of these require
kernel patches. The vanilla kernel offers the cryptoloop option
and a Device Mapper target (which is superior, as it supports all
file systems). If you want to use the cryptoloop, say Y to both
LOOP and CRYPTOLOOP, and make sure you have a recent (version 2.12
or later) version of util-linux. Additionally, be aware that
the cryptoloop is not safe for storing journaled filesystems.
Note that this loop device has nothing to do with the loopback
device used for network connections from the machine to itself.
config ADK_KPACKAGE_KMOD_BLK_DEV_NBD
prompt "kmod-nbd.......................... Network Block Device"
tristate
default n
help
Saying Y here will allow your computer to be a client for network
block devices, i.e. it will be able to use block devices exported by
servers (mount file systems on them etc.). Communication between
client and server works over TCP/IP networking, but to the client
program this is hidden: it looks like a regular local file access to
a block device special file such as /dev/nd0.
Network block devices also allows you to run a block-device in
userland (making server and client physically the same computer,
communicating using the loopback network device).
Read <file:Documentation/nbd.txt> for more information, especially
about where to find the server code, which runs in user space and
does not need special kernel support.
Note that this has nothing to do with the network file systems NFS
or Coda; you can say N here even if you intend to use NFS or Coda.

If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
any other SCSI device under Linux, say Y and make sure that you know
the name of your SCSI host adapter (the card inside your computer
that "speaks" the SCSI protocol, also called SCSI controller),
because you will be asked for it.
You also need to say Y here if you have a device which speaks
the SCSI protocol. Examples of this include the parallel port
version of the IOMEGA ZIP drive, USB storage devices, Fibre
Channel, FireWire storage and the IDE-SCSI emulation driver.

Device-mapper is a low level volume manager. It works by allowing
people to specify mappings for ranges of logical sectors. Various
mapping types are available, in addition people may write their own
modules containing custom mappings if they wish.
Higher level volume managers such as LVM2 use this driver.

This device-mapper target allows you to create a device that
transparently encrypts the data on it. You'll need to activate
the ciphers you're going to use in the cryptoapi configuration.
