Linux vs Windows Round 0: A Microsoft Dev Builds the Linux Kernel In an insightful YouTube video titled "Linux vs Windows Round 0: A Microsoft Dev Builds the Linux Kernel," retired Microsoft developer Dave Plummer dives deep into the workings of the Windows Subsystem for Linux (WSL) v2, demonstrating how to build and deploy a custom Linux kernel right on Windows 10. This engaging presentation is particularly compelling for users who want to explore the powerful integration of Linux capabilities within the Windows environment, highlighting a remarkable intersection of two historically rival operating systems.

Overview of WSL2​

Plummer introduces viewers to WSL2, an enhanced version allowing the Linux kernel to run natively on Windows through the Windows Hypervisor. He explains that WSL2 addresses performance issues that were prominent in its predecessor, WSL1, by allowing direct communication between the Linux kernel and hardware, reducing the overhead typically associated with such layers of abstraction. This shift brings nearly bare-metal performance for the Linux environment running atop Windows, an exciting prospect for developers and power users alike.

Building a Custom Linux Kernel​

Throughout the video, Plummer methodically guides viewers through the process of compiling a custom Linux kernel using Ubuntu within WSL. This involves configuring the kernel, installing necessary tools via the Advanced Package Tool (APT), and ultimately building the kernel using a simple command. He emphasizes the practicality of running both Linux and Windows applications simultaneously, offering a blend of flexibility and high performance.

Key Features and Benefits​

1. Native Performance: With WSL2, the Linux environment operates with minimal latency, achieving performance close to a native Linux installation.
2. Ease of Use: The installation process for WSL is straightforward, requiring only basic command line interactions. Plummer even refers to a "chicken and egg" problem that users may encounter, reassuring them that getting started is easier than it seems.
3. Integration with Windows: The ability to run Linux applications side-by-side with Windows applications adds tremendous value. Users can leverage Linux tools alongside their usual Windows software, enhancing productivity in development workflows.
4. Open-source Collaboration: Plummer discusses the importance of using Microsoft's kernel enlistments for compatibility, promising an easier path for users not wanting to delve into the complexities of building from source.
