ELI5: Explain Like I'm 5

CRIU

Okay little one, do you know what a computer program is? It's like a set of instructions that tell a computer what to do.

Now, let's talk about another thing called a "process." It's kind of like a mini program running on a computer. And sometimes, we need to move a process from one computer to another.

But here's the problem, when we move a process, it can lose important things like its data or its place in line to run on the computer. That's where CRIU comes in!

CRIU stands for "Checkpoint/Restore In Userspace." It's a special program that helps move our mini program (process) from one computer to another without losing its important information.

You can think of it like putting a bookmark in your favorite book. When you close the book and come back to it later, you can use the bookmark to pick up right where you left off. CRIU does something similar for computer processes. It bookmarks their place so that they can be moved without losing their important information.

Overall, CRIU helps make sure our computer processes stay safe and don't lose anything important when we move them around.
