CTF isn't strictly needed to use DTrace, though. [Off-topic] Pity that we do not have /dev/ksyms that exposes the actual (in-memory) kernel layout as an ELF object. Also, it's a pity that our crashdump format does not provide for saving a kernel along a memory dump (esp. given that a size of the former << a size of the latter). -- Andriy Gapon
