Rocky Linux 9 arrives today, bringing a slew of new security, application, and networking features. But what has the potential to take center stage in version 9 is the availability of all the build chain infrastructure tools that developers will need to take Rocky Linux to enhance or reinvent the operating system, whether they are independently from the community or any upstream supporting. wish to do something. organization. As a result, Rocky Linux v9 provides a supported enterprise Linux platform for the next decade.

Rocky Linux uses only open source tools to deliver a fully reproducible operating system, ensuring that there is no recurrence of CentOS end-of-life issues.

“When we release any version of Rocky Linux, it is more than just a bunch of binaries, package repositories and installers,” said Gregory Kurtzer, CEO of CIQ and founder of Rocky Enterprise Software Foundation (RESF), Linux, the unit behind Rocky. “With Rocky version 8, we used Cozy, the Fedora build system. But, with version 9, CIQ has created a fully cloud native build stack called Peridot that we have given to REST and the world. Peridot allows anyone to recompile, build, enhance, and manage Rocky Linux as we do. Additionally, each Rocky Linux release is supported by the community, by the community. 100% built in the open. They are managed by RESF with all our infrastructure and secure materials like keys and secure boot shims. This is our commitment to our users and community from day one, this ensuring that Rocky Linux will always be freely available and community controlled.”

Rocky Linux usage boom

Data provided by Fedora from the Additional Package for Enterprise Linux (EPEL) usage metrics shows a rapid increase in Rocky Linux usage among EPEL capable people. In particular, data shows that Rocky Linux is used more than CentOS Streams, AlmaLinux, and even RHEL. This is depicted graphically courtesy of Michael Larabel at Photonics, where data shows utility numbers continue to grow, outpacing all other enterprise Linux variants. (more on EPEL)

create system details

Rocky Linux 9 was built with a community-developed and open-source cloud native build system called Peridot, which is built in Golang. Peridot was used to build Rocky Linux 9 for the x86_64, aarch64, s390x and ppc64le architectures. A primary goal in developing the new build system was to ensure that new versions of Rocky could be released within a week of the release of each Red Hat Enterprise Linux new version. The source code for the build system is available at, and soon it will be easily installed via Helm Charts for anyone to take advantage of.

security enhancement

Security advancements in Rocky 9 include:

  • The use of SHA-1 message digests for cryptographic purposes is deprecated, as the cryptographic hash functions produced by SHA-1 are no longer considered secure.
  • OpenSSL is now version 3.0.1 with several improvements, including provider concepts, new versioning scheme, an improved HTTP(S) client, support for new protocols, formats and algorithms, and more.
  • OpenSSH is now version 8.7p1 with several improvements, most notably the replacement of the SCP/RCP protocol with the SFTP protocol which provides more predictable filename handling.
  • SELinux performance, memory overhead, loading time, and more have been greatly improved.
  • Rocky Linux 9 supports automatic configuration of security compliance settings for PCI-DSS, HIPAA, DISA and more directly through the Anaconda installer, saving time and effort for meeting complex requirements.

new networking features

Key networking changes in Rocky 9 include:

  • mptcpd or multipath tcp daemon can be used instead of iproute2 to configure multipath tcp endpoints.
  • NetworkManager now uses key files to store new connection profiles as the default, but still supports the use of ifcfg.
  • iptables-nft and ipset are now deprecated including utilities, iptables, ip6tables, ebtables and arptables. All of these have been replaced by the nftables framework.
  • The network-scripts package has been deprecated. Use NetworkManager to configure network connections.
