dnf greets Fedora
dnf is a fork of the venerable yum package manager. It is build on hawkey, a library allowing clients to query and resolve dependencies of RPM packages based on the current state of RPMDB and yum repositories.
dnf in Fedora 18 is a technical preview, and is installed alongside yum. It should not yet be used on critical production machines, but early adopters are promised a more efficient, faster package management utility.
Dwarf Compressor compacts debug files
Fedora 18 debuginfo has been post-processed by a DWARF compressor tool to reduce size of the *.debug files.
systemctl assumes it works with services
systemctl, the utility used to administer services and other systemd targets, will now assume that it is working with a service. Administrators will no longer have to append '.service' to the name of the daemon they are administering. For example,
systemctl restart dhcpd will now just work, but previous releases required
systemctl restart dhcpd.service.
Terminals get more colorful
Fedora now features supporting terminal emulators using 256 colors by default. With new environment variables, applications such as gnome-terminal, konsole, and screen will automatically be enabled with 256 color support. Other applications can display 256 colors but must be configured. While still disabled by default, users can enable color terminals for connecting remote systems with the environment variable SEND_256_COLORS_TO_REMOTE. These configurations can be found in /etc/profile.d/256color.sh
Remote management gets better with Agent-Free Systems Management
On systems that contain IPMI compliant Service Processors, it is now possible to have closer integration of OS and Service Processor without the need for 3rd party software. This will enable better management of the system remotely.
WBEM and CIF management tools extended
WEBM and CIF are two of the DTMF standards for enterprise system management. With Fedora 18, this class of software is greatly expanded manage as well as monitor remote systems.
Administrators can use these utilities to administer network interfaces, storage objects, services, power state, users, and software packages. They can also monitor system load, usage, and more.
All of this functionality can be accessed through a web or command line interface that efficiently handles large numbers of systems. Documentation is provided with sblim-cmpi-* or cura-* packages.
