examples vary - trivial one is: debug tools like omapconf[1] or testing
tools like opentest[2] need some standard way to ensure Linux kernel is
functional - trusting the least set of parameters is usually what we
would prefer. while building a generic distro such as debian or yocto,
one prefers NOT to need to do a package build per SoC/perboard - that
never scales. instead, you'd like the same application run on different
systems dynamically.
