Some System V 8*4882a593Smuzhiyun Unixes can create and mount hard disk partitions and diskettes using 9*4882a593Smuzhiyun this file system as well. Saying Y here will allow you to read from 10*4882a593Smuzhiyun these partitions; if you also want to write to them, say Y to the 11*4882a593Smuzhiyun experimental "UFS file system write support", below. Please read the 12*4882a593Smuzhiyun file <file:Documentation/admin-guide/ufs.rst> for more information. 13*4882a593Smuzhiyun 14*4882a593Smuzhiyun The recently released UFS2 variant (used in FreeBSD 5.x) is 15*4882a593Smuzhiyun READ-ONLY supported. 16*4882a593Smuzhiyun 17*4882a593Smuzhiyun Note that this option is generally not needed for floppies, since a 18*4882a593Smuzhiyun good portable way to transport files and directories between unixes 19*4882a593Smuzhiyun (and even other operating systems) is given by the tar program ("man 20*4882a593Smuzhiyun tar" or preferably "info tar"). 21*4882a593Smuzhiyun 22*4882a593Smuzhiyun When accessing NeXTstep files, you may need to convert them from the 23*4882a593Smuzhiyun NeXT character set to the Latin1 character set; use the program 24*4882a593Smuzhiyun recode ("info recode") for this purpose. 25*4882a593Smuzhiyun 26*4882a593Smuzhiyun To compile the UFS file system support as a module, choose M here: the 27*4882a593Smuzhiyun module will be called ufs. 28*4882a593Smuzhiyun 29*4882a593Smuzhiyun If you haven't heard about all of this before, it's safe to say N. 30*4882a593Smuzhiyun 31*4882a593Smuzhiyunconfig UFS_FS_WRITE 32*4882a593Smuzhiyun bool "UFS file system write support (DANGEROUS)" 33*4882a593Smuzhiyun depends on UFS_FS 34*4882a593Smuzhiyun help 35*4882a593Smuzhiyun Say Y here if you want to try writing to UFS partitions.
