An installer ISO for FreeBSD-current (June 8) with John's DTrace work is available here: http://people.freebsd.org/~lawrance/7-CURRENT-jb-dtrace-i386- disc1.iso.bz2 If you are curious to try it but don't want to install -current, you may be able to try it from the Fixit shell. For example: Fixit# kldconfig /dist/boot/kernel Fixit# kldload dtrace systrace profile fbt Fixit# dtrace -n 'open:entry{@[copyinstr(arg0)] = count()}' & <do stuff> Fixit# kill `jobid %1`
