1# SPDX-License-Identifier: GPL-2.0-only2config UFS_FS3 tristate "UFS file system support (read only)"4 depends on BLOCK5 select BUFFER_HEAD6 help7 BSD and derivate versions of Unix (such as SunOS, FreeBSD, NetBSD,8 OpenBSD and NeXTstep) use a file system called UFS. Some System V9 Unixes can create and mount hard disk partitions and diskettes using10 this file system as well. Saying Y here will allow you to read from11 these partitions; if you also want to write to them, say Y to the12 experimental "UFS file system write support", below. Please read the13 file <file:Documentation/admin-guide/ufs.rst> for more information.14 15 The recently released UFS2 variant (used in FreeBSD 5.x) is16 READ-ONLY supported.17 18 Note that this option is generally not needed for floppies, since a19 good portable way to transport files and directories between unixes20 (and even other operating systems) is given by the tar program ("man21 tar" or preferably "info tar").22 23 When accessing NeXTstep files, you may need to convert them from the24 NeXT character set to the Latin1 character set; use the program25 recode ("info recode") for this purpose.26 27 To compile the UFS file system support as a module, choose M here: the28 module will be called ufs.29 30 If you haven't heard about all of this before, it's safe to say N.31 32config UFS_FS_WRITE33 bool "UFS file system write support (DANGEROUS)"34 depends on UFS_FS35 help36 Say Y here if you want to try writing to UFS partitions. This is37 experimental, so you should back up your UFS partitions beforehand.38 39config UFS_DEBUG40 bool "UFS debugging"41 depends on UFS_FS42 help43 If you are experiencing any problems with the UFS filesystem, say44 Y here. This will result in _many_ additional debugging messages to be45 written to the system log.46
