The beta release of the AlmaLinux 9 distribution has been introduced, built using packages from the Red Hat Enterprise Linux 9 branch and containing all the changes proposed in this release. The builds are prepared for x86_64, ARM64, s390x, and ppc64le architectures in the form of bootable (780 MB), minimal (1.7 GB), and full images (8 GB). RHEL 9 and AlmaLinux 9 releases are expected in early May. <\/p>\n
The distribution is identical to RHEL in functionality, with the exception of changes related to rebranding and the removal of RHEL-specific packages such as redhat-*, insights-client, and subscription-manager-migration*. AlmaLinux is free for all categories of users, developed with community involvement, and utilizing a management model similar to that of the Fedora project. The creators of AlmaLinux aimed to achieve an optimal balance between corporate support and community interests \u2014 on one side, resources and developers from CloudLinux, which has extensive experience in maintaining RHEL forks, are engaged in the development, while on the other side, the project is transparent and under community control. <\/p>\n
The AlmaLinux distribution is based on CloudLinux, which, despite utilizing its resources and developers, has transferred the project to an independent non-profit organization, the AlmaLinux OS Foundation, for neutral development involving the community. A million dollars per year has been allocated for the project's development. All AlmaLinux developments are published under open licenses. <\/p>\n
Key changes in AlmaLinux 9 and RHEL 9 compared to the RHEL 8 branch: <\/p>\n
\n
The system environment and build tools have been updated. GCC 11 is used for building packages. The standard C library has been upgraded to glibc 2.34. The Linux kernel package is based on the 5.14 release. The RPM package manager has been updated to version 4.16, which includes integrity checking support through fapolicyd. <\/li>\n
The migration of the distribution to Python 3 has been completed. The default branch proposed is Python 3.9. Python 2 is no longer supplied. <\/li>\n
The desktop is based on GNOME 40 (RHEL 8 shipped with GNOME 3.28) and the GTK 4 library. In GNOME 40, virtual desktops in the Activities Overview are transitioned to a horizontal layout, displayed as a continuously scrollable chain from left to right. Each desktop shown in the overview clearly presents the open windows, which employ dynamic panning and scaling during user interaction. Seamless transitioning is provided between the application list and virtual desktops. <\/li>\n
GNOME utilizes the power-profiles-daemon handler, enabling on-the-fly switching between power-saving mode, balanced power consumption mode, and maximum performance mode. <\/li>\n
All audio streams have been transitioned to the PipeWire multimedia server, which is now used by default instead of PulseAudio and JACK. The use of PipeWire allows the typical desktop edition to offer capabilities for professional audio processing, eliminate fragmentation, and unify the audio infrastructure for various applications. <\/li>\n
By default, the GRUB boot menu is hidden if RHEL is the only distribution installed on the system and if the last boot was successful. To display the menu during boot, simply hold down the Shift key or press the Esc or F8 key multiple times. Changes in the bootloader also include the placement of GRUB configuration files for all architectures in one directory \/boot\/grub2\/ (the file \/boot\/efi\/EFI\/redhat\/grub.cfg is now a symbolic link to \/boot\/grub2\/grub.cfg), meaning the same installed system can be booted using either EFI or BIOS. <\/li>\n
Components for various language support have been moved to langpacks, allowing for varying levels of installed language support. For example, the langpacks-core-font package offers only fonts, the langpacks-core package provides the locale for glibc, the basic font, and input method, while langpacks includes translations, additional fonts, and dictionaries for spell checking. <\/li>\n
Components have been updated for security purposes. A new branch of the OpenSSL 3.0 cryptographic library has been implemented in the distribution. More modern and reliable cryptographic algorithms are enabled by default (for example, the use of SHA-1 in TLS, DTLS, SSH, IKEv2, and Kerberos is prohibited, and support for TLS 1.0, TLS 1.1, DTLS 1.0, RC4, Camellia, DSA, 3DES, and FFDHE-1024 has been disabled). The OpenSSH package has been updated to version 8.6p1. Cyrus SASL has switched to the GDBM backend instead of Berkeley DB. Support for the DBM (Berkeley DB) format has been discontinued in the NSS (Network Security Services) libraries. GnuTLS has been updated to version 3.7.2. <\/li>\n
The performance of SELinux has significantly improved, and memory consumption has decreased. The setting for \"SELINUX=disabled\" has been removed from \/etc\/selinux\/config to disable SELinux (this setting now only disables the loading of policies; to actually disable SELinux functionality, the kernel must now be passed the parameter \"selinux=0\"). <\/li>\n
