Hi Alex!
For all sysfs entries there *should* be a corresponding sysctl for it.
Do sysctl -Na | grep create_child and you might find the node that you
seek. After that all you need to do is call sysctl <node>=0x800c and it
should achieve the same thing as setting the sysfs node.
Please note that you must be the patch attached to
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/174213 in order for things
to function properly as the sysfs handling code is still broken on HEAD.
I've CCed Jeff Roberson about it a few times, and asked for assistance from
Xin as well as I haven't gotten any feedback from Jeff.
Thanks,
-Garrett
