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.
