182 | The User-Mode Linux port includes a driver called UBD which will let | |

190 | ---help--- | |
191 | Writes to the virtual block device are not immediately written to the | |
192 | host's disk; this may cause problems if, for example, the User-Mode | |
193 | Linux 'Virtual Machine' uses a journalling filesystem and the host | |
194 | computer crashes. | |
195 | ||
196 | Synchronous operation (i.e. always writing data to the host's disk | |
197 | immediately) is configurable on a per-UBD basis by using a special | |
198 | kernel command line option. Alternatively, you can say Y here to | |
199 | turn on synchronous operation by default for all block devices. | |
200 | ||
201 | If you're running a journalling file system (like reiserfs, for | |
202 | example) in your virtual machine, you will want to say Y here. If | |
203 | you care for the safety of the data in your virtual machine, Y is a | |
204 | wise choice too. In all other cases (for example, if you're just | |

212 | tristate "Loopback device support" | |
213 | ---help--- | |
214 | Saying Y here will allow you to use a regular file as a block | |
215 | device; you can then create a file system on that block device and | |
216 | mount it just as you would mount other block devices such as hard | |
217 | drive partitions, CD-ROM drives or floppy drives. The loop devices | |
218 | are block special device files with major number 7 and typically | |
219 | called /dev/loop0, /dev/loop1 etc. | |
220 | ||
221 | This is useful if you want to check an ISO 9660 file system before | |
222 | burning the CD, or if you want to use floppy images without first | |
223 | writing them to floppy. Furthermore, some Linux distributions avoid | |
224 | the need for a dedicated Linux partition by keeping their complete | |
225 | root file system inside a DOS FAT file using this loop device | |
226 | driver. | |
227 | ||
228 | To use the loop device, you need the losetup utility, found in the | |
229 | util-linux package, see | |
230 | <ftp://ftp.kernel.org/pub/linux/utils/util-linux/>. | |
231 | ||
232 | The loop device driver can also be used to "hide" a file system in | |
233 | a disk partition, floppy, or regular file, either using encryption | |
234 | (scrambling the data) or steganography (hiding the data in the low | |
235 | bits of, say, a sound file). This is also safe if the file resides | |
236 | on a remote file server. | |
237 | ||
238 | There are several ways of encrypting disks. Some of these require | |
239 | kernel patches. The vanilla kernel offers the cryptoloop option | |
240 | and a Device Mapper target (which is superior, as it supports all | |
241 | file systems). If you want to use the cryptoloop, say Y to both | |
242 | LOOP and CRYPTOLOOP, and make sure you have a recent (version 2.12 | |
243 | or later) version of util-linux. Additionally, be aware that | |
244 | the cryptoloop is not safe for storing journaled filesystems. | |
245 | ||
246 | Note that this loop device has nothing to do with the loopback | |
247 | device used for network connections from the machine to itself. | |
248 | ||
249 | To compile this driver as a module, choose M here: the | |
