Not yet on FreeBSD, unless there's something I'm missing. Some work needs to be done on the port in order to get it working. hotspot/make/bsd/makefiles/dtrace.make only does anything if it detects that it's running on Darwin; that'd probably be a good place to start for anyone interested in working on this. -Mark Hi Mark, Noted and thanks. The Postgresql port (9.3, not sure for 8.4/9.1/9.2) have dtrace support, which is very cool.

There would have to be an updated spec for those, and it would be a bit of a PITA to use. I suspect the "right" answer for this on x86 is UEFI. -- John Baldwin
