I've just updated my system to r273822:

[root at taiga:~]# uname -a
FreeBSD taiga 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r273822: Wed

The world and kernel are in sync. I'm still running the kernel built 
after the same config as before. But, unfortunately, I've missed the 
ability to run dtrace scripts. What have I missed ?

[root at taiga:~]# config -x /boot/kernel/kernel | egrep -i 'debug|kdtrace|ctf'

Thanks.
