Some comments: Last time I tried, I didn't see any problems by adding makeoptions WITH_CTF=yes to the kernel config instead of doing make WITH_CTF=1 kernel Did I miss something, and if not, shouldn't we tell about the makeoptions part instead (a kernel rebuild later will not cause trouble when someone forgets to do the WITH_CTF part as it is already in the kernel makefile)? What is DDB_CTF doing? Some additional dtrace access in ddb? I didn't had it before but the dtrace probes I had in KLDs worked without problems when running dtrace probes from userland.
