Choosing Alternatives


Some services in Fedora and RHEL can be implemented by several different software packages. Although you can, you probably don't want to run multiple mail and print servers on the same computer. At the very least, you should set the software you want to use by default.

In Fedora and RHEL, an alternatives feature is packaged into the operating system. Alternatives is an implementation of the Debian GNU/Linux alternatives feature. In essence, alternatives links the software you choose (or leave by default) into the common locations where the service being implemented is launched or made available.

Cross-Reference 

See the "Choosing Software Alternatives" section in Chapter 10 for more information on the alternatives feature.

The first services to be implemented under alternatives in Fedora and RHEL were print and mail server packages. However, when the LPRng print service was dropped from Fedora and RHEL, it left mail as the only service that's supported by the alternatives feature.

Assuming you have multiple mail agents .

Figure B-1 shows an example of the system-switch-mail window.
