Services which may be enabled by default

Only services that meet the criteria below are permitted to be enabled by default on package installation.

For the purposes of this document, a "service" is defined as one or more of:

Restrictions

Installation of the package providing the unit auto-started by this preset may not change the behavior of any other service running (or potentially running) on the system.

Locally running services

If a service does not require manual configuration to be functional and does not listen on a network socket for connections originating on a separate physical or virtual machine, it may be enabled by default (but is not required to do so).

Example: Local D-BUS services

Non-persistent services

In addition, any service which does not remain persistent on the system (aka, it "runs once then goes away"), does not listen to incoming connections during initialization, and does not require configuration to be functional may be enabled by default (but is not required to do so).

Example: iptables

Approved Exceptions

Some services which are permitted to be enabled by default as specific exceptions. Services that should be enabled by default throughout all of Fedora must be approved by FESCo. Services that should be enabled or disabled by default only on one or more of the Fedora Editions must be approved by those Editions' Working Groups.

Example:

  • FESCo approves openssh-server to run by default on Fedora in general.
  • Workstation WG approves openssh-server to be disabled by default on the Workstation Edition.

Current list of enabled/disabled services

How to enable a service by default

Unit files must correspond to the Fedora Packaging Guidelines. Services are enabled or disabled by default through systemd preset files. Preset files can be overridden by a local administrator, but a set of defaults are provided by Fedora.

If the service should be enabled by default, it must be added to one of the distribution presets files (see above).

For services which meet one of the conditions listed above, a ticket should be filed in bugzilla. If the preset should be changed for versions other than rawhide, indicate that in the ticket.
