The Source Ruckus Kernel-Builder is a utility for automating building the Linux kernel, creating a universal initrd using RuckusRD, and wrapping it all up into a self-extracting kernel installer. The resulting installer can be installed locally or can install itself on a list of remote hosts via SSH.

Execute this inside an already configured (e.g., via make menuconfig) kernel
source tree.
usage: kernel-builder OPTIONS...
-h, --help Show this help message and exit.
-V, --version Show version string and exit.
-K, --kernel-only Just compile the kernel and install its files in
$PWD/FOO.
-k, --kernel-and-initrd Stop after generating the initrd via RuckusRD and
installing it in $PWD/FOO/boot. Basically, stop
before creating the installer. This can be usefull
for testing new kernel configurations before you're
really ready to install and/or distribute the
kernel.
-n, --numjobs=N Use N jobs for compiling. Default is CPUCOUNT+1,
which should peg CPU usage at 100% on most systems
and result in the fastest build times. If you want
to use less CPU and let the compilation take more
time, specify a smaller value for N with this
option.
-s, --stable Build 'stable' kernel. This results in /boot files
being named with a trailing .y instead of the point
release number, so you don't have to update the
bootloader config after installation. There's also
a .y symlink in /lib/modules and /usr/src pointing
to the appropriately versioned directories as well
as installation code to move the symlink and remove
old files. The idea here is that installing 5.10.42
should completely replace all of 5.10.41's files and
require only a simple reboot w/out any other
reconfiguration to get into the new kernel.
-t, --test Build 'test' kernel. These kernels have 'test' in
filenames instead of a version string. This option
is for facilitating quick bisect jobs, where you're
compiling different kernel versions and rebooting
over and over w/out having to reconfigure the
bootloader every single time.
