RHEL8

RHEL 8 has now been released.

Here are some aspects of it:

• it uses the dnf command instead of yum with an identical syntax (yum is an alias for dnf),
• the file system Btrfs, once in technical preview, is no longer available,
• concerning the Python language used for most of the system scripts, the version 3.6 will replace Python 2.7 (more details here),
• about LDAP, OpenLDAP is no longer available, you have to use the 389 LDAP server or something else,
• you can’t remove NetworkManager from your configuration (it was already the case with the Gnome graphical environment in RHEL 7.5),
• KDE is removed from the desktop (KDE is deprecated according to the RHEL 7.6 release notes),
• a new mechanism called application stream is introduced (more details are available here and here).
