I am working on a tool that makes an image snapshot of a bootable HFS volume. If the volume can be unmounted, that's an easy task. But when it's the boot volume, this doesn't work, of course.
Now, I've seen that DFA in Sierra seems to be able to lock a volume so that it can verify and possibly repair it.
How does DFA do that? Is there some OS function I could use for that purpose, too?
