Well, there is a first time for everything. In my many years of dabbling with Linux, this is the first time I had experience a 1-minute kernel build. I achieved it by using a compilation cluster using distcc.
As the image shows, nearly the entire kernel compilation was distributed over a number of machines. As a result, the kernel compiled successfully in about 1-minute as measured using the wall clock.
Furthermore, the compilation cluster was not made up of super fast machines but was mainly a collection of old machines:
- 3x Intel E5800
- 2x Intel E2180
I used the standard Debian commands to build the latest 3.19 kernel from kernel.org which are:
make-kpkg --jobs 40 --rootcmd fakeroot --config oldconfig --initrd --us --uc kernel_image
Impressive achievement for a bunch of old machines used as LTSP thin clients.
