No /usr/src installed by kernel-headers-system-docker

I am trying to install sysdig, which needs kernel headers to build a kernel module. I am following

$ sudo ros service enable kernel-headers-system-docker
$ sudo ros service up kernel-headers-system-docker

There is no /usr/src on my RancherOS-0.8.1 EC2 instance after I run those commands. Shouldn’t there be?

The headers are installed into /lib/modules/4.9.16-rancher/build for v0.9.0 - or a similar versioned directory for whichever kernel you’re running at the time.

did you ever get sysdig working?
