It’s amazing what happens when you do any kind of research. Many times, you find a few interesting things around one topic you are looking into. First, I published a post about changing a process name which describes how it can be accomplished on different operating systems. This was the main point of my research. Then I described how to install other operating systems using grub2-bhyve on bhyve hypervisors. Today, the last topic is somewhat related to them. When I was looking at the process title it was easy to notice that the kernel needed to read some piece of memory from it. What would happen if the memory region didn’t exist?
