Now that you have written your first kernel module, it's time to take
off the training wheels and move on to building a custom kernel. No
more distro kernels for you, for this task you must run your own kernel.
And use git! Exciting isn't it! No, oh, ok...
The tasks for this round is:
- download Linus's latest git tree from git.kernel.org (you have to
figure out which one is his, it's not that hard, just remember what
his last name is and you should be fine.)
- build it, install it, and boot it. You can use whatever kernel
configuration options you wish to use, but you must enable
- show proof of booting this kernel. Bonus points for you if you do
it on a "real" machine, and not a virtual machine (virtual machines
are acceptable, but come on, real kernel developers don't mess
around with virtual machines, they are too slow. Oh yeah, we aren't
real kernel developers just yet. Well, I'm not anyway, I'm just a
script...) Again, proof of running this kernel is up to you, I'm
sure you can do well.
Hint, you should look into the 'make localmodconfig' option, and base
your kernel configuration on a working distro kernel configuration.
Don't sit there and answer all 1625 different kernel configuration
options by hand, even I, a foolish script, know better than to do that!
After doing this, don't throw away that kernel and git tree and
configuration file. You'll be using it for later tasks, a working
kernel configuration file is a precious thing, all kernel developers
have one they have grown and tended to over the years. This is the
start of a long journey with yours, don't discard it like was a broken
umbrella, it deserves better than that.
