Do you have a kernel environment per vimage? If not, you could still have per-vimage variables that are settable via tunables look at kenv during vimage creation to parse any tunables perhaps. However, that is possibly tricky since you can sometimes use sysctl.conf to override a setting done via loader.conf and in that case, what value should a new vimage get? -- John Baldwin
