IN-PLACE UPGRADE
Red Hat Enterprise Linux 7 beta provides support that simplies the task of performing in-place
upgrades. A pre-upgrade assistant package is provided in the Red Hat Enterprise Linux 6.5 beta
zstream, which reports what can be upgraded in-place and what will have to be done manually.
The report describes the issues and links to knowledgebase articles available in the Red Hat
Customer Portal.
The report includes information on conguration les that will be modied and identies existing
user-modied conguration les, recommending some to be manually checked. At that point, the
administrator can decide if the end result of an in-place upgrade is sufcient for their needs. Upon
executing the in-place upgrade, the administrator can then inspect the nal results and decide to
complete the upgrade.
PARTITIONING DEFAULTS FOR ROLLBACK
The ability to revert to a known, good system conguration is crucial in a production environment.
Using LVM snapshots with ext4 and XFS (or the integrated LVM snapshotting feature in Btrfs) an
administrator can capture the state of a system and preserve it for future use. An example use case
would involve an in-place upgrade that does not present a desired outcome and an administrator
who wants to restore the original conguration.
ANACONDA KICKSTART FOR ACTIVE DIRECTORY INTEGRATION
A system administrator can now create kickstart installation les that do not require administrative
credentials. The installed system can then join an Active Directory domain with a one-time password.
This new feature eliminates the need for writing and maintaining large blocks of interdependent
code in two domains.
CREATING INSTALLATION MEDIA
Red Hat Enterprise Linux 7 beta introduces Live Media Creator for creating customized installa-
tion media from a kickstart le for a range of deployment use cases. Media can be used to deploy
standardized images whether on standardized corporate desktops, standardized servers, virtual
machines, or hyperscale deployments. Live Media Creator, especially when used with templates,
provide a way to control and manage congurations across the enterprise.
SERVER PROFILE TEMPLATES
Red Hat Enterprise Linux 7 beta features the ability to use installation templates to create servers
for common workloads. These templates can simplify and speed creating and deploying Red Hat
Enterprise Linux servers, even for those with little or no experience with Linux.
desktoP
Red Hat Enterprise Linux 7 beta includes three desktops to match different work styles and
preferences: GNOME 3, GNOME Classic, and KDE.
GNOME 3 provides a focused working environment that encourages productivity. A powerful
search feature lets you access all your work from one place. Side-by-side windows make it easy
to view several documents at the same time, and you can turn off notications when you need to
concentrate on the task in hand.
