dtrace is pretty good stuff. It originates from OpenSolaris just like ZFS.
It is a freamwork (and scripting language)
for tracing and performance mesurments of whole system with small overhead.

dtrace is also avaible in Mac OS X, and FreeBSD.

ZFS and dtrace are two most interesting parts of the cool stuff taken
from Solaris and merged into FreeBSD. Not only interesting,
but also usefull and very good in design and implementation.

It currently looks similar that it is probably just a matter of
packaging dtrace utils and it's libs, and maybe small minor tweaks in
libc/ld.so, to make tracing of other libs easier.

(there are similar projects for Linux, but similary like btrfs-ZFS
war, they are still not mature as dtrace).

In 7.2 and 8.0 kernel config i see that KDTRACE_HOOKS is commented out.
Also ZFS is not there.

It is really important to have all this things differencing from Linux
in kFreeBSD: ZFS, dtrace, pf, clean architecture.

Another important part (which can bring people) is Xen domU support.
I'm actually trying to write scripts to make it simple to
use (install) kfreebsd as Xen domU under Linux Lenny / Squezee dom0.

PS. Nice presentation. S5 is next of my favorite presentation systems (after beamer :D )
