During the past month, I had to do all tmpfs development on my laptop. This includes coding and testing. If you have ever done any kernel hacking you know what this means: reboot every now and then to test your changes, which can drive you crazy after few reboots (specially if things keep breaking).

So when I got back home, the first thing I did was to set up a machine I had lying around for kernel testing exclusively. The machine is a Pentium 133Mhz with 32MB of RAM and a 3GB hard disk, more than enough for my purposes. (I'd have also used qemu... but since I had the hardware...)

Here are some details about its configuration, designed to minimize manual intervention:

With this setup, whenever I have built a new kernel in my development machine, I can instantly reboot the testing machine, press RETURN when asked for it and see the results. No need to copy the kernel to the second box in any way nor to enter any command!
