WHAT IS THIS DRIVER?
|
|
==================
|
|
This module implements the native filesystem of BeOS http://www.beincorporated.com/
|
|
for the linux 2.4.1 and later kernels. Currently it is a read-only
|
|
implementation.
|
|
|
|
Which is it, BFS or BEFS?
|
|
================
|
|
Be, Inc said, "BeOS Filesystem is officially called BFS, not BeFS".
|
|
But Unixware Boot Filesystem is called bfs, too. And they are already in
|
|
the kernel. Because of this naming conflict, on Linux the BeOS
|
|
filesystem is called befs.
|
|
|
|
HOW TO INSTALL
|
|
==============
|
|
step 1. Install the BeFS patch into the source code tree of linux.
|
|
|
|
Apply the patchfile to your kernel source tree.
|
|
Assuming that your kernel source is in /foo/bar/linux and the patchfile
|
|
is called patch-befs-xxx, you would do the following:
|
|
|
|
cd /foo/bar/linux
|
|
patch -p1 < /path/to/patch-befs-xxx
|
|
|
|
if the patching step fails (i.e. there are rejected hunks), you can try to
|
|
figure it out yourself (it shouldn't be hard), or mail the maintainer
|
|
(Will Dyson <will_dyson@pobox.com>) for help.
|
|
|
|
step 2. Configuration & make kernel
|
|
|
|
The linux kernel has many compile-time options. Most of them are beyond the
|
|
scope of this document. I suggest the Kernel-HOWTO document as a good general
|
|
reference on this topic. http://www.linuxdocs.org/HOWTOs/Kernel-HOWTO-4.html
|
|
|
|
However, to use the BeFS module, you must enable it at configure time.
|
|
|
|
cd /foo/bar/linux
|
|
make menuconfig (or xconfig)
|
|
|
|
The BeFS module is not a standard part of the linux kernel, so you must first
|
|
enable support for experimental code under the "Code maturity level" menu.
|
|
|
|
Then, under the "Filesystems" menu will be an option called "BeFS
|
|
filesystem (experimental)", or something like that. Enable that option
|
|
(it is fine to make it a module).
|
|
|
|
Save your kernel configuration and then build your kernel.
|
|
|
|
step 3. Install
|
|
|
|
See the kernel howto <http://www.linux.com/howto/Kernel-HOWTO.html> for
|
|
instructions on this critical step.
|
|
|
|
USING BFS
|
|
=========
|
|
To use the BeOS filesystem, use filesystem type 'befs'.
|
|
|
|
ex)
|
|
mount -t befs /dev/fd0 /beos
|
|
|
|
MOUNT OPTIONS
|
|
=============
|
|
uid=nnn All files in the partition will be owned by user id nnn.
|
|
gid=nnn All files in the partition will be in group nnn.
|
|
iocharset=xxx Use xxx as the name of the NLS translation table.
|
|
debug The driver will output debugging information to the syslog.
|
|
|
|
