Improved Performance
Overlay2 generally offers better performance compared to its predecessor Overlay. It reduces the number of layers that need to be copied and improves efficiency by sharing common files between images.
Lower Disk Usage
By using a copy-on-write mechanism, Overlay2 helps reduce disk space usage. It allows multiple images to share the same files, which avoids unnecessary duplication of data.
Simplified Management
Overlay2 simplifies management of image layers and file systems, which can lead to easier debugging and maintenance. Its improved structure makes image operations more straightforward.
Wider Compatibility
Overlay2 is widely supported on modern Linux distributions and is designed to work seamlessly with various versions, offering good compatibility.

Kernel Dependency
The performance and features of Overlay2 are highly dependent on the underlying Linux kernel version. A newer kernel version may be required to unlock all features.
Limited Non-Linux Support
Overlay2 is specifically designed for Linux and may not be supported on other operating systems, limiting its use cases to Linux environments only.
Potential for Complexity
Despite improvements, Overlay2 can still introduce complexity in some use cases, especially when dealing with a large number of image layers that need to be managed carefully.
Potential for Performance Degradation
In scenarios where many layers are heavily modified, Overlay2 can experience performance degradation due to the increased overhead of managing multiple layers.
