Finally, Delinea (Centrify) has added support for RHCOS, AlmaLinux x86_64, Rocky Linux. Good news indeed
As we continue to bolster our PAM solutions for Linux, the latest release of Server Suite adds support for RHCOS, AlmaLinux x86_64, and Rocky Linux.
Red Hat Enterprise Linux CoreOS (RHCOS) is a container-optimized operating system for running containers at scale. Both Rocky Linux and AlmaLinux are binary-compatible with Red Hat Enterprise Linux (RHEL) and have emerged as a viable alternative to CentOS.

Delinea announces support for AlmaLinux and Rocky Linux
If after a reboot and if you do a “nvidia-smi” and receive an error like the one
# nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
# ./mlnxofedinstall
Current operation system is not supported!
Step 2b: Force Install with the right distro.
# ./mlnxofedinstall --distro rhel8.5 --force

Step 3: You have to remove and reload the drivers before you can do the /etc/init.d/openibd restart
When you logged on to Rocky Linux 8.5, you may see this message.
Activate the web console with: systemctl enable --now cockpit.socket
This system is not registered to Red Hat Insights. See https://cloud.redhat.com/
To register this system, run: insights-client --register
If you wish to disable the message, you may want to
rm -f /etc/motd.d/cockpit
The command will remove the symlink to file /run/cockpit/motd

In Rocky Linux 8.5, the ntp package is no longer supported and it is implemented by the chronyd (a daemon that runs in user-space) which is provided in the chrony package.
chrony works both as an NTP server and as an NTP client, which is used to synchronize the system clock with NTP servers.
To install the chrony suite, use the DNF Package Manager.

A Linux® container is a set of 1 or more processes that are isolated from the rest of the system. All the files necessary to run them are provided from a distinct image, meaning Linux containers are portable and consistent as they move from development to testing, and finally to production. This makes them much quicker to use than development pipelines that rely on replicating traditional testing environments. Because of their popularity and ease of use containers are also an important part of IT security. Read more

The purpose of this blog post is to provide the steps required to implement NVMe-oF using RDMA over Converged Ethernet (RoCE) for SUSE Enterprise Linux (SLES) 15 and subsequent releases.
An important item to note is that RoCE requires a lossless network, requiring global pause flow control or PFC to be configured on the network for smooth operation.
All of the below steps are implemented using Mellanox Connect-X4 adapters.
