Speaking about the version it shows if this is an SMP kernel, and if the
kernel is preemtible, IOW build with CONFIG_PREEMPT

Now, how many preemtible kernels are running systemd?

And by coincidence, here we are speaking about systemd-analyze :-)

Not to mention the build time stamp that will tell you if two same
kernels differ... used in the embedded world.

Sure, David posted a nice video of it, during the last systemd hackfest :-)

Ok, if you are against it, I'll just update the patch and drop it,
I didn't bother, just fix the bug and keep the old behaviour. The code
that adds this is really small.
