Because the mud settles from the announcement of IBM’s pending acquisition of Crimson Hat, work continues undaunted in delivering new merchandise. This week sees the primary beta launch of Crimson Hat Enterprise Linux (RHEL) eight, Crimson Hat’s venerable enterprise distribution, which additionally serves as the idea for CentOS and Oracle Linux. For reference, RHEL is predicated on Fedora, which simply celebrated the discharge of Fedora 29.
By way of safety, the most important adjustments in RHEL eight are help for OpenSSL 1.1.1 and TLS 1.three, which a press launch notes “[enable] server functions on the platform to make use of the newest requirements for cryptographic safety of buyer knowledge.” Likewise, the brand new launch consists of “System-wide Cryptographic Insurance policies” permitting for cryptographic configuration utilizing a unified interface, fairly than needing to work with particular functions.
For desktop customers, Crimson Hat has taken the marginally daring transfer of utilizing Wayland because the default show server for Gnome Show Supervisor (GDM), although X.Org continues to be out there. The transition to Wayland in Fedora has been uneven up thus far, as NVIDIA continues to ship drivers which aren’t totally appropriate with Wayland, and Wayland doesn’t but help distant desktop entry. Neither of those components ought to current points for enterprise customers, as GDM handles primarily the login display screen, not consumer classes.

For customers of Fedora, one specific distinction between the 2 is using YUM four fairly than DNF for package deal administration. Essentially, YUM four is predicated on DNF, and (largely) preserves backward compatibility with present scripts, with the upper efficiency that DNF has already provided for a number of releases of Fedora. A full rationalization of the advantages of DNF over YUM (and subsequently, adjustments between RHEL 7 and eight) is accessible right here.
RHEL eight additionally consists of help for for open container toolkits, together with the Buildah (container imaging/constructing), Podman (container runtime) and Skopeo (container sharing and discovering) utilities, in addition to help for the Stratis file system, file system snapshots, and LUKSv2 disk encryption with Community-Certain Disk Encryption (NBDE).
The brand new launch does deprecate some older applied sciences. By default, Python shouldn’t be put in, although the default implementation is Python three.6. Restricted help for Python 2.7 exists, although that is for transition functions, as Python 2 won’t be maintained upstream previous January 1, 2010, whereas help for RHEL eight will proceed for a number of years afterward. For workstation installations, KDE help has been eliminated. RHEL 7 shipped with KDE four, which is finish of life. Crimson Hat shouldn’t be providing KDE Plasma 5, and the improve path from KDE on RHEL 7 to GNOME on RHEL eight is unsupported. Moreover, help for btrfs has been eliminated.
You may obtain the Crimson Hat Enterprise Linux eight beta right here. A CentOS variant of the beta construct is unlikely to be forthcoming, as having one unified beta simplifies bug reporting.
The large takeaways for tech leaders:
- That is the primary beta launch of Crimson Hat Enterprise Linux (RHEL) eight, which additionally serves as the idea for CentOS and Oracle Linux. The preliminary launch of RHEL 7 was in June 2014.
- RHEL eight brings help for OpenSSL 1.1.1 and TLS 1.three, in addition to container instruments Buildah, Podman, and Skopeo, and the Stratis file system, whereas deprecating Python 2 and eradicating KDE four and btrfs fully.
