DevConf.US 2022

There have been a number of advancements in both storage and the Linux boot process in recent years. This talk aims to take a look at the process for fully supporting Stratis, a userspace volume manager, in early boot. While many newer Linux storage solutions are kernel based, our process for early boot support can provide some insight into design recommendations, usability considerations, and best practices for userspace volume management code in early boot. This talk will primarily focus on how best to abstract complexity in the boot process for storage solutions and provide simple, usable interfaces for projects aimed at user experience while designing a robust systems solution. The audience will gain understanding with how to integrate a device mapper stack and daemon in early boot using Stratis root filesystem support.
