dnf-bootc

The goal is to make an image-based OS, feel like a package-based OS.

/var/dnf-bootc commands are applied live and persist after reboot.

/var/rpm-ostree-to-bootc is another tool provided that can assist with rpm-ostree to bootc migrations

Installation

curl -fsSL https://raw.githubusercontent.com/ericcurtin/dnf-bootc/s/install.sh | sudo bash

Usage

Because we are not packaged properly yet, we have to call as /var/dnf-bootc.

/var/dnf-bootc uses the same syntax as dnf:

sudo /var/dnf-bootc install <package_name>

/var/rpm-ostree-to-bootc usage:

sudo /var/rpm-ostree-to-bootc quay.io/namespace/some-container-image:version

Features

• Automatically appends install/remove packages transactions to /var/Containerfile.
• Rebuilds using podman build after each transaction.
• Only triggers when using /var/dnf-bootc command, not when using dnf command.

Features not automatically appended to os Containerfile

Only installs and removes are automatically appended. Other features should be run and appended to /var/Containerfile manually. /var/Containerfile relies on keeping the state in sync with the local system, by appending a RUN command to a previously known state in the /var/Containerfile.

An example of a feature that /var/dnf-bootc doesn't automatically account for would be, adding a third party repo. To do this, we may add lines to /var/Containerfile like this:

RUN dnf config-manager --add-repo repository

Followed by:

sudo cp /var/Containerfile /var/.Containerfile

This tells /var/dnf-bootc, we are happy to make manual changes to the /var/Containerfile, outside of it's management.

Followed by:

sudo dnf-bootc config-manager --add-repo repository
