7a276a52fSAlexey Dobriyan	  BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,
8a276a52fSAlexey Dobriyan	  OpenBSD and NeXTstep) use a file system called UFS. Some System V
9a276a52fSAlexey Dobriyan	  Unixes can create and mount hard disk partitions and diskettes using
10a276a52fSAlexey Dobriyan	  this file system as well. Saying Y here will allow you to read from
11a276a52fSAlexey Dobriyan	  these partitions; if you also want to write to them, say Y to the
12a276a52fSAlexey Dobriyan	  experimental "UFS file system write support", below. Please read the
13aa95b4a9SMauro Carvalho Chehab	  file <file:Documentation/admin-guide/ufs.rst> for more information.

15a276a52fSAlexey Dobriyan          The recently released UFS2 variant (used in FreeBSD 5.x) is
16a276a52fSAlexey Dobriyan          READ-ONLY supported.
17a276a52fSAlexey Dobriyan
18a276a52fSAlexey Dobriyan	  Note that this option is generally not needed for floppies, since a
19a276a52fSAlexey Dobriyan	  good portable way to transport files and directories between unixes
20a276a52fSAlexey Dobriyan	  (and even other operating systems) is given by the tar program ("man
21a276a52fSAlexey Dobriyan	  tar" or preferably "info tar").
22a276a52fSAlexey Dobriyan
23a276a52fSAlexey Dobriyan	  When accessing NeXTstep files, you may need to convert them from the
24a276a52fSAlexey Dobriyan	  NeXT character set to the Latin1 character set; use the program
25a276a52fSAlexey Dobriyan	  recode ("info recode") for this purpose.

27a276a52fSAlexey Dobriyan	  To compile the UFS file system support as a module, choose M here: the
28a276a52fSAlexey Dobriyan	  module will be called ufs.

30a276a52fSAlexey Dobriyan	  If you haven't heard about all of this before, it's safe to say N.
