Pull request overview
Adds a new draft Interrupt post describing logging strategies for resource-constrained embedded Linux devices, focusing on flash wear, RAM pressure, and practical daemon/configuration tradeoffs.
Changes:
- Introduces a new draft article covering kernel logging, syslog vs journald, and storage/rate-limiting considerations.
- Adds example configurations (journald.conf options and a Fluent Bit pipeline) plus references.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

| **How much should you actually log?** Severity levels let you dial verbosity up for active debugging and down for production, but the real lever for device longevity isn't the volume of logs you generate, it is how much of that volume actually gets written to flash, how often, and in what size chunks. Concretely, that means filtering relevant logs, rate-limiting logs as early as possible, and moving anything you only need to *count* out of the log stream and into a metric. | ||

| None of these are settings you get right once and forget. Rather, they are tradeoffs worth revisiting as a device's fleet, firmware, and failure modes evolve. Getting them right is what separates a logging architecture that helps you debug a fleet in the field from one that quietly wears out the flash underneath it. |

I really like this closing, nice!

Good topic, and good axes (tools and tradeoffs) to look at it with - excited to get this one added to the library! |

I know you can technically hit merge with my approval, but would appreciate one last pass from our benevolent interrupt leaders (@bahildebrand / @gminn others?) before I start giving full "ship it" approval, in case there's any best practices/preferences I missed :) |

Adds a new draft article covering Embedded Linux logging strategies for resource-constrained devices. It walks through various different logging daemons available and ideas to help reduce overall log volume while still preserving critical information for debugging devices.
