30 This module implements the native filesystem of BeOS <http://www.be.com/>
31 for the linux 2.4.1 and later kernels. Currently it is a read-only implementation.
33 Which is it, BFS or BEFS?
35 Be, Inc said, "BeOS Filesystem is officially called BFS, not BeFS".
36 But Unixware Boot Filesystem is called bfs, too. And they are already in the
38 Because of this nameing conflict, on Linux the BeOS filesystem is called befs.
42 step 1. Install the BeFS patch into the source code tree of linux.
44 Apply the patchfile to your kernel source tree.
45 Assuming that your kernel source is in /foo/bar/linux and the patchfile is called
46 patch-befs-xxx, you would do the following:
49 patch -p1 < /path/to/patch-befs-xxx
51 if the patching step fails (i.e. there are rejected hunks), you can try to
52 figure it out yourself (it shouldn't be hard), or mail the maintainer
53 (Will Dyson <will_dyson@pobox.com>) for help.
55 step 2. Configuretion & make kernel
57 The linux kernel has many compile-time options. Most of them are beyond the
58 scope of this document. I suggest the Kernel-HOWTO document as a good general
59 reference on this topic. <http://www.linux.com/howto/Kernel-HOWTO.html>
61 However, to use the BeFS module, you must enable it at configure time.
64 make menuconfig (or xconfig)
66 The BeFS module is not a standard part of the linux kernel, so you must first
67 enable support for experimental code under the "Code maturity level" menu.
69 Then, under the "Filesystems" menu will be an option called "BeFS filesystem (experimental)",
70 or something like that. Enable that option (it is fine to make it a module).
72 Save your kernel configuration and then build your kernel.
76 See the kernel howto <http://www.linux.com/howto/Kernel-HOWTO.html> for
77 instructions on this critical step.
81 To use the BeOS filesystem, use filesystem type 'befs'.
84 mount -t befs /dev/fd0 /beos
88 uid=nnn All files in the partition will be owned by user id nnn.
89 gid=nnn All files in the partition will be in group nnn.
90 iocharset=xxx Use xxx as the name of the NLS translation table.
91 debug The driver will output debugging information to the syslog.
