Before you start
This tutorial shows you how to install and use JFS under Linux. JFS is an enterprise journalling filesystem technology currently used by IBM enterprise servers and now being ported to Linux.
The JFS sources are well organized and freely available, and the JFS development team is actively seeking contributions from the Linux community. If you have the skills and desire to improve upon the kernel, JFS would be an excellent place to start.
Some experience compiling your own Linux kernel is helpful. If you haven't had a chance to compile your own kernel, read the tutorial "Compiling the Linux kernel" as a starting point, and then return to this JFS tutorial.
