# SPDX-License-Identifier: GPL-2.0-only config UFS_FS tristate "UFS file system support (read only)" depends on BLOCK select BUFFER_HEAD help BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD, OpenBSD and NeXTstep) use a file system called UFS. Some System V Unixes can create and mount hard disk partitions and diskettes using this file system as well. Saying Y here will allow you to read from these partitions; if you also want to write to them, say Y to the experimental "UFS file system write support", below. Please read the file <file:Documentation/admin-guide/ufs.rst> for more information. The recently released UFS2 variant (used in FreeBSD 5.x) is READ-ONLY supported. Note that this option is generally not needed for floppies, since a good portable way to transport files and directories between unixes (and even other operating systems) is given by the tar program ("man tar" or preferably "info tar"). When accessing NeXTstep files, you may need to convert them from the NeXT character set to the Latin1 character set; use the program recode ("info recode") for this purpose. To compile the UFS file system support as a module, choose M here: the module will be called ufs. If you haven't heard about all of this before, it's safe to say N. config UFS_FS_WRITE bool "UFS file system write support (DANGEROUS)" depends on UFS_FS help Say Y here if you want to try writing to UFS partitions. This is experimental, so you should back up your UFS partitions beforehand. config UFS_DEBUG bool "UFS debugging" depends on UFS_FS help If you are experiencing any problems with the UFS filesystem, say Y here. This will result in _many_ additional debugging messages to be written to the system log.
