Does anyone have an idea of how Dragonfly might fare in such a kernel exploit examination? Getting rid of Linux compat was probably a very good idea. But how about the rest of the kernel space?

someone should register DFly for Coverity scans… This should give us some ideas how DFly does against FreeBSD (https://scan.coverity.com/projects/FreeBSD) etc.
