Let's face it, system tap isn't going to be merged, so why even bring it
up? Every kernel developer I have _ever_ seen agrees that all the new
tracing is a million times superior. I'm sure there are system tap people
who disagree, but quite frankly, I don't see it being merged considering
how little the system tap people ever did for the kernel.
So if things like system tap and "security models that go behind the
kernel by tying into utrace" are the reasons for utrace, color me utterly
uninterested. In fact, color me actively hostile. I think that's the worst
possible situation that we'd ever be in as kernel people (namely exactly
the "do things in kernel space by hiding behind utrace without having
kernel people involved")
