+ tristate "FreeVxFS file system support (VERITAS VxFS(TM) compatible)"
+ depends on BLOCK
+ help
+ FreeVxFS is a file system driver that support the VERITAS VxFS(TM)
+ file system format. VERITAS VxFS(TM) is the standard file system
+ of SCO UnixWare (and possibly others) and optionally available
+ for Sunsoft Solaris, HP-UX and many other operating systems.
+ Currently only readonly access is supported.
+
+ NOTE: the file system type as used by mount(1), mount(2) and
+ fstab(5) is 'vxfs' as it describes the file system format, not
+ the actual driver.
+
+ To compile this as a module, choose M here: the module will be
+ called freevxfs. If unsure, say N.
