Deep dives into DevOps and server-side topics, combining theory with hands-on examples. Run every command in an attached remote playground, from your browser or local terminal over SSH — no setup required.
Understand how the chroot system call changes the root directory for a process, learn how dynamic linkers resolve dependencies inside a jail, and see what an isolated process perceives as its filesystem root.
A container image and a bootable root filesystem are not the same artifact. This tutorial builds both from the same Dockerfile so you can see exactly where they diverge: what a plain ubuntu:24.04 is missing, the five requirements an iximiuz Labs playground rootfs has to satisfy, and how to prove an image would boot without being able to boot it. Ends with the same image built the easy way, from the official rootfs base.
