+Some extra care is needed when using liblttng-ust with daemon
+applications that call fork(), clone(), or BSD rfork() without a
+following exec() family system call. The library "liblttng-ust-fork.so"
+needs to be preloaded for the application (launch with e.g.
+LD_PRELOAD=liblttng-ust-fork.so appname).
