Piranha is not kernel related. It's a piece of software, just as vi,
apache or whatever.

I think you're misunderstand the way it works. The load balancing of
incoming requests is handled by IPVS (from linuxvirtualserver), which is
a kernel module (or kernel built-in feature, your choice). IPVS is
*enough* to do load balacing. But you might (actually, in a serious
setup, must) need a user-space program that configures IPVS and checks
the availability of the real servers. This can be acheived using piranha
(amongst others).

If you're talking high availability (and not load balancing), then IPVS
is not involved, and piranha can do it, but it's still a user-space
program, unrelated to the kernel.

The short answer is no. But you can still ship a distro containing an
IPVS enabled kernel plus a recent piranha package.
