ELI5: Explain Like I'm 5

UnionFS

Okay kiddo, let’s talk about unionfs. Imagine you have two boxes of toys. One box has your cars and the other box has your dolls. Unionfs is like having both boxes open at the same time, and you can play with all the toys together.

In computer terms, unionfs is a type of file system that lets you combine two or more directories together into one. So, if you have a directory with some files and another directory with different files, unionfs lets you access all the files at the same time in one directory. It’s like having all the files in one big toy box that you can play with.

This is useful for when you are working on a project and have files scattered in different directories. With unionfs, you can combine all the files together and work on them in one place. It also helps with backup and storage, as you can have all your files in one location without having to move them around.

Unionfs works by creating a virtual file system, which means it’s not really a physical thing like your toy boxes. It’s like magic! The virtual file system combines the different directories together and shows them as one directory.

So, there you have it, unionfs is like combining two toy boxes into one big toy box, or like combining different directories into one virtual file system. Pretty cool, huh?
