If there is one single thing that should serve as the take-away from the RHEL7 beta testing, it is this – “Everyone needs to re-learn some things”!
Here are some screenshots that illustrate the point:
1. The installer screen looks sparse and not graphical at all.
2. Even the media check is now in a console-style appearance (not curses/n-curses appearance)
3. Language selection may be confusing for some. Select with mouse or type the language you need. No testing, though.
4. This is Beta software. Red Hat would like you to resist the urge to deploy it in production use. Fair warning.
5. We now have a summary style. Individual items may be re-visited.
6. Some tasks are run in parallel to installation. Remember Ubuntu, anyone?
7. First boot screen – we are now in kernel 3.x. Finally!
8. Login screen. same old same old
9. Notice that init got replaced with systemd? This one feature will make most system administrators go back to the class room to understand how they can leverage the Systemd utilities to create their custom scripts/run-level links.
CURIOUS to know the changes in RHEL7? Why not read the release notes?
Here are some of the interesting ones:
- GRUB 2
- The default file system for an Anaconda-based installation of Red Hat Enterprise Linux 7.0 Beta is now XFS, which replaces the Fourth Extended Filesystem (ext4) used by default in Red Hat Enterprise Linux 6. The ext4 and Btrfs (B-Tree) file systems can be used as alternatives to XFS
- The nmcli tool is introduced to allow users and scripts to interact with NetworkManager
- Networking Teaming has been introduced as an alternative to bonding for link aggregation. It is designed to be easy to maintain, debug and extended. For the user it offers performance and flexibility improvements and should be evaluated for all new installations
- Journal (versatile logging functionality)
- GNOME 3
- KDE 4.10
- MariaDB 5.5
