| 6 | BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD, |
| 7 | OpenBSD and NeXTstep) use a file system called UFS. Some System V |
| 8 | Unixes can create and mount hard disk partitions and diskettes using |
| 9 | this file system as well. Saying Y here will allow you to read from |
| 10 | these partitions; if you also want to write to them, say Y to the |
| 11 | experimental "UFS file system write support", below. Please read the |

| 14 | The recently released UFS2 variant (used in FreeBSD 5.x) is |
| 15 | READ-ONLY supported. |
| 16 | |
| 17 | Note that this option is generally not needed for floppies, since a |
| 18 | good portable way to transport files and directories between unixes |
| 19 | (and even other operating systems) is given by the tar program ("man |
| 20 | tar" or preferably "info tar"). |
| 21 | |
| 22 | When accessing NeXTstep files, you may need to convert them from the |
| 23 | NeXT character set to the Latin1 character set; use the program |
| 24 | recode ("info recode") for this purpose. |
| 25 | |
| 26 | To compile the UFS file system support as a module, choose M here: the |
| 27 | module will be called ufs. |

| 29 | If you haven't heard about all of this before, it's safe to say N. |
