Red Hat has just announced that it's releasing the next beta for Red Hat Enterprise Linux (RHEL) 8.2. Even at this early stage, RHEL 8.2 looks like a release most Red Hat users will want to adopt.
As Red Hat sysadmin Christian Labisch observed, the ability to register your system, attach RHEL subscriptions, and install from the Content Delivery Network (CDN) before package installation is "a huge improvement."
You can use this release with both interactive GUI installations and automated Kickstart installations. It comes with a host of benefits such as:
RHEL 8.2 Beta also enables system admins to start checking scenarios with in-place upgrades from RHEL 6/7 to RHEL 8, Since RHEL 6 is nearing the end of its support life in November 2020, this is an important update.
The new Beta also extends RHEL's monitoring and performance capabilities with the introduction of Performance Co-Pilot (PCP) 5.02. This now comes with new collection agents for Microsoft SQL Server 2019 on Linux.
For programmers, 8.2 adds tighter integration with the extended Berkeley Packet Filter (eBPF). This is an in-kernel virtual machine that allows code execution in the kernel space. Brendan Gregg, a Netflix senior performance architect, described this as a "fundamental change to a 50-year-old kernel model by introducing a new interface for applications to make kernel requests, alongside syscalls." Gregg continued: It "allows you to write kernel mode applications that can access resources and run with high performance and efficiency with guarantees of security."
On other platforms eBPF is already being used for a wide variety of tasks. In RHEL 8.2, you'll be able to use the following eBPF components:
The following eBPF components are available as a Technology Preview:
Red Hat has long supported language updates ahead of RHEL releases in such packages as Red Hat Software Collections. In RHEL 8, Application Streams brought the latest developer languages, runtimes and other tools to RHEL. This gives your programmers access to the latest tools, while maintaining main operating system release stability. In the RHEL 8.2 beta: developers will get GCC Toolset 9.1; Python 3.8 and Maven 3.6.
