1# SPDX-License-Identifier: GPL-2.0-only 2config UFS_FS 3 tristate "UFS file system support (read only)" 4 depends on BLOCK 5 select BUFFER_HEAD 6 help 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. 14 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. 29 30 If you haven't heard about all of this before, it's safe to say N. 31 32config UFS_FS_WRITE 33 bool "UFS file system write support (DANGEROUS)" 34 depends on UFS_FS 35 help 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. 38 39config UFS_DEBUG 40 bool "UFS debugging" 41 depends on UFS_FS 42 help 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. 46
