Some System V 8a276a52fSAlexey Dobriyan Unixes can create and mount hard disk partitions and diskettes using 9a276a52fSAlexey Dobriyan this file system as well. Saying Y here will allow you to read from 10a276a52fSAlexey Dobriyan these partitions; if you also want to write to them, say Y to the 11a276a52fSAlexey Dobriyan experimental "UFS file system write support", below. Please read the 12aa95b4a9SMauro Carvalho Chehab file <file:Documentation/admin-guide/ufs.rst> for more information. 13a276a52fSAlexey Dobriyan 14a276a52fSAlexey Dobriyan The recently released UFS2 variant (used in FreeBSD 5.x) is 15a276a52fSAlexey Dobriyan READ-ONLY supported. 16a276a52fSAlexey Dobriyan 17a276a52fSAlexey Dobriyan Note that this option is generally not needed for floppies, since a 18a276a52fSAlexey Dobriyan good portable way to transport files and directories between unixes 19a276a52fSAlexey Dobriyan (and even other operating systems) is given by the tar program ("man 20a276a52fSAlexey Dobriyan tar" or preferably "info tar"). 21a276a52fSAlexey Dobriyan 22a276a52fSAlexey Dobriyan When accessing NeXTstep files, you may need to convert them from the 23a276a52fSAlexey Dobriyan NeXT character set to the Latin1 character set; use the program 24a276a52fSAlexey Dobriyan recode ("info recode") for this purpose. 25a276a52fSAlexey Dobriyan 26a276a52fSAlexey Dobriyan To compile the UFS file system support as a module, choose M here: the 27a276a52fSAlexey Dobriyan module will be called ufs. 28a276a52fSAlexey Dobriyan 29a276a52fSAlexey Dobriyan If you haven't heard about all of this before, it's safe to say N. 30a276a52fSAlexey Dobriyan 31a276a52fSAlexey Dobriyanconfig UFS_FS_WRITE 32a276a52fSAlexey Dobriyan bool "UFS file system write support (DANGEROUS)" 33b7e17a10SKees Cook depends on UFS_FS 34a276a52fSAlexey Dobriyan help 35a276a52fSAlexey Dobriyan Say Y here if you want to try writing to UFS partitions.
