The commands (including the make command for the kernel) are as follows:

# cd /boot

# cp -R kernel kernel.good

# cd /usr/src

This will install the kernel in /boot/kernel

# make KERNCONF=MYKERNELNAME buildkernel

# cd /boot

# mv kernel kernel.mykernelname

# mkdir kernel

# cp kernel.good/* kernel/

# nextboot -k kernel.mykernelname

Upon reboot, the system will load kernel.mykernelname and then erase the part of the configuration that told it to load kernel.mykernelname

Consequently, subsequent reboots will load the kernel located in /boot/kernel which is the original kernel

Assuming that kernel.mykernelname loaded successfully, you can run the following commands to make the new kernel permanent:

# mv /boot/kernel /boot/kernel.previous

# mv /boot/kernel.mykernalname /boot/kernel

For those who are curious, here is the NSA's take on their guides:

NSA initiatives in enhancing software security cover both proprietary and open source software, and we have successfully used both proprietary and open source models in our research activities. NSA’s work to enhance the security of software is motivated by one simple consideration: use our resources as efficiently as possible to give NSA’s customers the best possible security options in the most widely employed products. The objective of the NSA research program is to develop technologic advances that can be shared with the software development community through a variety of transfer mechanisms. NSA does not favor or promote any specific software product or business model. Rather, NSA is promoting enhanced security.

Similarly, AT&T stores will sell phones which are based on Android.  This is an exciting event.  For the first time, much of America will save money on replacing cell phones because of software malfunction.   The Linux kernel was designed with preemptive multitasking since day one. Job control and process scheduling within the Linux kernel have been extensively worked on for several decades. Linux memory management is very efficient.  Linux has solid, reliable, and efficient user-space and kernel-space thread implementations.  Interestingly enough, Palm has announced that it will be moving to a Linux based operating system. 

Windows was initially created as a cooperative multitasking, operating system. Microsoft finally realized that they needed to be using preemptive multitasking.  When they realized this, SYSV and BSD development communities already had years of experience programming preemptive multitasking kernels.  Consequently, Microsoft modified their kernel code to use preemptive multitasking. 

The move to Linux based mobile operating systems could ultimately save quite a bit of money for consumers.

This particular guitar has a prominent history. Namely, it was played by Jerry Garcia on the first Dead album. The album was released in 1967.

In their later years, Weir reportedly used Pyramids and Jerry played on Vinci strings.

His latest book,  Risk Management Solutions for Sarbanes-Oxley Section 404 IT Compliance, is a required read for all professionals working in regulated environments.
