Available eLxr 12 Images

You can download images from eLxr website. Images include package management by default, to help you customize your distribution to meet your needs.

eLxr 12 Images include:

  • Intel x86 and AMD EPYC:

    • elxr-edge-12.10.0.0-amd64.iso - This eLxr Edge 12 OSTree-based image, for use with edge devices, requires minimal installation, such as specifying the installation drive and optionally specifying drive and kernel parameters

    • elxr-cloud-amd64-12.10.1.0.qcow2 - This eLxr Edge 12 cloud-based image, for use in virtual environments, requires you to customize a cloud-init configuration file to provision it as a virtual machine.

    • elxr-12.10.0.0-amd64-NETINST-1.iso - This full eLxr Server 12 image with the installer prompts you to perform an installation; for use with x86-based devices, such a PCs and servers.

  • ARM:

    • elxr-minimal-ostree-imx-12.10.0.0-arm64.img.zst - This live ARM boot image does not require installation, boots to a root prompt, and is optimized for the NXP i.MX8M, i.MX8+, and i.MX9 SoCs, for use with edge devices and virtual image solutions. To leverage the built-in graphics processing, you must update the firmware and install additional packages. For details, see Enable 3D Graphics Support and GNOME Desktop on NXP SoC Hardware.

    • elxr-orin-jetson-tegra-12.10.0.0-arm64.img.zst - This live ARM boot image is for NVIDIA Jetson AGX Orin hardware, boots to a root prompt, and is optimized for the NVIDIA Orin platform. Similar to other eLxr images, this live image boots to a standard console. To leverage the NVIDIA graphics processor available on AGX Orin hardware, you must add the additional binaries available from NVIDIA. For details, see Enable Full Graphics and Multimedia Support for NVIDIA Jetson AGX Orin Hardware.

Image Verification

Each eLxr image also includes a corresponding .iso.sha256 or .iso.sha256.txt file with the image hash for the image at build time. You can use these hash files to verify your image is genuine. To do this, use the sha256sum command in Linux, or the certUtil command in Windows.

For Linux, first navigate to the directory where you downloaded the file, then run the command. The following example uses the eLxr Server image in a Linux command prompt.

$ cd ~/Downloads
$ sha256sum elxr-12.10.0.0-amd64-NETINST-1.iso

eae7a46750170ee8116700d8cf3c9d567780ff1e6d2e372e79d208b95fdb8e56 *elxr-12.10.0.0-amd64-NETINST-1.iso

Compare the hash value, in this example eae7a46750170ee8116700d8cf3c9d567780ff1e6d2e372e79d208b95fdb8e56, to the corresponding image .iso.sha256 file available at https://elxr.org/downloads. As long as the values match, the image is valid.

For Windows, use the following command from a command prompt.

$ cd C:\Users\yourname\Downloads
$ certUtil -hashfile elxr-12.10.0.0-amd64-NETINST-1.iso SHA256

SHA256 hash of elxr-12-amd64-NETINST-1.iso:
eae7a46750170ee8116700d8cf3c9d567780ff1e6d2e372e79d208b95fdb8e56
CertUtil: -hashfile command completed successfully.

Similar to the Linux example above, compare the output hash to the image .iso.sha256 file to ensure the values match.

Package Information

Each image includes package management with APT (apt) or apt-ostree by default, which allows you to add, update, and remove packages and also include additional package feeds.

Hardware Features

This includes support for external memory devices, such as a USB or SD flash drive.

Your hardware device must support UEFI (32-bit). This ensures a trusted boot environment and is a requirement for using eLxr.

Intel x86

eLxr 12 runs on x86-based hardware and was tested on the following Intel x86 platforms:

  • Skylake

  • Broadwell

  • Cascade Lake

  • Ice Lake

  • Sapphire Rapids

AMD x86 Platform

  • EPYC

Arm

eLxr 12 runs on Arm hardware and was validated on the following platforms:

  • NXP:

    • i.MX8

    • i.MX8+

    • i.MX93

  • nVdia Jetson AGX Orin

By default, these images do not include full graphics support, as proprietary firmware and drivers are necessary to include this functionality. To add graphics support, see the eLxr 12 Release Notes.

Security Features

The following security features apply to Intel x86 ISO images.

  • FIPS140-2 OpenSSL version 3.0.8 - a pre-certified OpenSSL implementation for FIPS140-2

  • Secure Boot - a self-signed secure boot implementation with the sbctl tool for managing Secure Boot keys. To use Secure Boot, you will need to set up your eLxr installation with new, self-signed keys. For details, see Enabling Secure Boot in eLxr 12.
