This pulls in a whole can of worms. Getting DTrace to work on FreeBSD is a little tricky, because certain commands/arguments must be provided manually during world/kernel "make" time and not via make.conf/src.conf. AFAIK this is still the case in RELENG_8, while "kludges and hacks" have been put in place on 9.x to work around this. I can provide some references to my claims if need be. There's also some segregation between DTrace-capable userland and DTrace-capable kernel, but the delineation between the two -- and how to accomplish one without the other -- is something I've never found any conclusive write-up on or otherwise. I think such an explanation would benefit many userland application authors/developers. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
