Re: DTrace for FreeBSD- source snapshots

Presumably since it's from Sun, it'll run on the FreeBSD/sparc64  
machines as well? ;)

Unfortunately, I don't have anything but i386 machines here (not  
counting a Powerbook), but how portable is this code? Can anybody  
verify it'll work on FreeBSD/amd64? mips? arm? leg?

I'm definitely interested in the prospects of being able to use this  
while working on L4::BSD, since dtrace seems almost perfect for  
debugging kernel and other low level processes without all the magic  
and pixie dust I hear jhb and phk use... ;)

Cheers,
