In mid-December it was finaly ready: The first public beta release of Red Hat Enterprise Linux 7 was made available for download. It will still take some time to an official release of this version, it is expected date of mid-2014. A first look at the beta version delivers interesting news.
Red Hat bids farewell to the 32-bit architecture: the beta version of RHEL 7 is currently only available for the 64 -bit architecture ( x86_64). Other hardware options are IBM Power (7 and 8) and IBM System z.
The default file system format is now XFS, as alternatives ext4 and btrfs are available. However, whether btfrs is already officially supported with RHEL 7.0 or if it gets the status of a Technology Preview, remains to be seen.
To start services systemd replaces the previously used upstart. Confirmation that upstart could not be established successfully in the enterprise Linux environment (including the upcoming SUSE Linux Enterprise Server 12 with also uses systemd). Systemd is a service manager and not just a starting mechanism. Design goals include a better account of the dependencies between processes and a faster boot times by highly parallelized. A novelty compared to the starting mechanisms used so far is the ability to start services when necessary to monitor (such as classical, via the xinetd), and services and, where appropriate, to start them again. However, all new systemd features, should be largely compatible with the classic sysvinit and LSB scripts.
Changes in the management of subscriptions: The previously used registration via Red Hat Network is replaced by the Red Hat Subscription Manager and the command: subscription-manager.
There are also some changes in the area of high availability: The Cluster Manager rgmanager is replaced by Pacemaker, which has proven its suitability for everyday use with a number of other Linux distributions. By switching to Pacemaker it also becomes necessary to depart from the previous administration and configuration tools (ccs, ricci, luci). The new administration tool is now pcs (Pacemaker Configuration System).
