Originally developed for the Vali/MollenOS operating system, this is a generic package management system that is built as a lightweight alternative to current package managers. Its not only for package management, but also as an application format. The CHEF toolchain is made up of several parts, including tools for building and distribution CHEF packages.
bake The bake utility serves as the builder, and orchestrates everything related to generation of bake packages. Bake packages serve both as packages and application images that can be executed by serve.
order Order handles the orchestration of the online segment. Order controls your account setup, downloading of packages, package query and is the gateway to serve
serve Serve is the application backend. This needs to be implemented on an OS basis. This means if you seek to support chef applications, you need to implement serve for your OS.
In addition to those, the CHEF toolchain comes with 3 different daemons implementing different features. The served daemon provides the runtime of CHEF packages, allowing those to be executed in containerized environments.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install vchef, simply use the following command:
sudo snap install vchef
Browse and find snaps from the convenience of your desktop using the snap store snap.
