What is Springdale Linux?
Springdale Linux (formerly known as PUIAS Linux) is a Linux distribution that aims to provide a stable, reliable, and compatible operating system derived from the source code of Red Hat Enterprise Linux (RHEL). It is built from the same sources used by Red Hat for their enterprise offering, and it strives to maintain binary compatibility with RHEL. Springdale Linux is designed for users who require a stable and supported Linux distribution with long-term support (LTS) and security updates.
Springdale Linux is maintained by the Community Grids Laboratory at the University of Wisconsin-Madison and is a member of the CentOS derivative family. It offers a similar experience to CentOS, with a focus on providing a platform suitable for both desktop and server environments. Like CentOS, Springdale Linux aims to provide a free and open-source alternative to RHEL, allowing users to benefit from the stability and reliability of the RHEL ecosystem without the associated costs.
Key features of Springdale Linux include:
- Stability: Built from the same source code as RHEL, providing a stable and reliable platform for both desktop and server use.
- Compatibility: Strives to maintain binary compatibility with RHEL, ensuring compatibility with RHEL packages and applications.
- Long-Term Support: Offers long-term support (LTS) with security updates and maintenance releases.
- Community Support: Benefits from a supportive community of users and contributors who provide assistance and resources.
- Free and Open Source: Distributed under open-source licenses, allowing users to freely use, modify, and distribute the software.
Overall, Springdale Linux is a viable option for users seeking a stable, compatible, and community-supported Linux distribution based on RHEL source code. It provides an alternative to CentOS and other RHEL derivatives, catering to the needs of both individual users and organizations requiring a robust Linux operating system.

Environment Specification
We are using a minimal CentOS 8 virtual machine with following specifications.
- CPU – 3.4 Ghz (2 cores)
- Memory – 2 GB
- Storage – 20 GB
- Operating System – CentOS Linux 8.3
- Hostname – centos-8.centlinux.com
- IP Address – 192.168.116.230 /24
Check your Current Linux OS
Connect with centos-8.centlinux.com as root user with the help of a ssh client.
Execute following commands to check the version of your current Linux operating system.
# cat /etc/os-release NAME="CentOS Linux" VERSION="8" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="8" PLATFORM_ID="platform:el8" PRETTY_NAME="CentOS Linux 8" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:8" HOME_URL="https://centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-8" CENTOS_MANTISBT_PROJECT_VERSION="8" # cat /etc/centos-release CentOS Linux release 8.3.2011
Also check the version of your Linux Kernel.
# uname -r 4.18.0-240.1.1.el8_3.x86_64
Update your Linux Server
Update software packages of your CentOS Linux by using dnf command.
# dnf update -y
The process also update the Linux kernel, therefore, it is a good practice to reboot your operating system with new kernel.
# reboot
Remove CentOS Specific Software Packages
Before migrating to Springdale Linux, you have to remove software packages from your operating system related to CentOS branding and yum repositories.
Execute following command to remove CentOS specific software packages.
# rpm -e --nodeps centos-gpg-keys centos-linux-release centos-linux-repos
If you are migrating from a GUI based CentOS Linux then you must also remove centos-backgrounds, centos-indexhtml and centos-logos packages.
Install Springdale Linux Yum Repositories
To migrate our CentOS 8 operating system to Springdale Linux (SDL), you are required to install SDL yum repositories.
The latest stable release of Springdale Linux is 8.4, therefore we are installing yum repositories for the same.
# rpm -ivh http://springdale.princeton.edu/data/springdale/8.4/x86_64/os/BaseOS/Packages/{springdale-appstream-8-0.sdl8.2.noarch.rpm,springdale-core-8-0.sdl8.2.noarch.rpm,springdale-release-8.4-0.42.el8.x86_64.rpm}

Now, execute following dnf command to start migration process.
# dnf distro-sync -y
Reboot your Linux server with newly installed Linux kernel.
# reboot
GRUB menu has a newly entry pertains to Springdale Linux. Press <ENTER> to start your operating system with the new kernel.
After successful startup, you will reach at the Linux command line (CLI) based login prompt.
Login as root user.
Check your New Linux Operating System
Execute the following commands at Linux bash prompt to check the operating system version and other details.
# cat /etc/os-release NAME="Springdale Open Enterprise Linux" VERSION="8.4 (Modena)" ID="rhel" ID_LIKE="fedora" VERSION_ID="8.4" PLATFORM_ID="platform:el8" PRETTY_NAME="Springdale Open Enterprise Linux 8.4 (Modena)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:springdale:enterprise_linux:8.4:GA" HOME_URL="https://springdale.princeton.edu/" BUG_REPORT_URL="https://springdale.princeton.edu/bugzilla" REDHAT_BUGZILLA_PRODUCT="Springdale Open Enterprise Linux 8" REDHAT_BUGZILLA_PRODUCT_VERSION=8.4 REDHAT_SUPPORT_PRODUCT="Springdale Open Enterprise Linux" REDHAT_SUPPORT_PRODUCT_VERSION="8.4" # cat /etc/springdale-release Springdale Open Enterprise Linux release 8.4 (Modena)
Also check the version of your new Linux kernel.
# uname -r 4.18.0-305.7.1.el8_4.x86_64
