Create a chiseled filesystem

Learn how to create custom chiseled root filesystems (rootfs) using Chisel across different Ubuntu releases and CPU architectures.

In this tutorial, we cover three key deployment scenarios:

– Same architecture and release: Slice a filesystem matching the host OS (amd64, Ubuntu 22.04 LTS) using default parameters.

– Different Ubuntu release: Override default settings using –release to slice an Ubuntu 22.04 LTS filesystem from an Ubuntu 24.04 LTS host.

– Different architecture: Target a different CPU architecture using –arch to slice an arm64 filesystem on an amd64 host.

Each scenario is verified inside a sudo chroot environment to confirm application functionality.
