LinuxDevices: Migrating to Linux Kernel 2.6 — Part 1: Customizing a 2.6-based Kernel

“In addition to new features, each new stable Linux kernel
version provides many improvements that standardize its internal
interfaces, extend the performance and size of supported devices,
and simplify adding support for new devices and subsystems to the
kernel. Some of these changes are only relevant to kernel
developers or people writing device drivers, while others impact
system startup, system administration, and application
deployment.

“If you are migrating existing applications to a 2.6-based Linux
distribution such as TimeSys Linux, its performance improvements
and increased support for industry-wide standards such as POSIX
make porting a relatively simple task. However, if you are
migrating device drivers, custom system-level applications, or a
customized Linux root filesystem to 2.6-based Linux, an overview of
the basic changes to kernel internals, subsystems, system startup,
and system administration can save you a substantial amount of
development time and debugging headaches…”
