7 BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,
8 OpenBSD and NeXTstep) use a file system called UFS. Some System V
9 Unixes can create and mount hard disk partitions and diskettes using
10 this file system as well. Saying Y here will allow you to read from
11 these partitions; if you also want to write to them, say Y to the
12 experimental "UFS file system write support", below. Please read the
13 file <file:Documentation/admin-guide/ufs.rst> for more information.

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

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

36 Say Y here if you want to try writing to UFS partitions. This is
37 experimental, so you should back up your UFS partitions beforehand.

43 If you are experiencing any problems with the UFS filesystem, say
44 Y here. This will result in _many_ additional debugging messages to be
45 written to the system log.
