# What Settings Are Currently Available For Transient Units?
|
|
|
|
Our intention is to make all settings that are available as unit file settings
|
|
also available for transient units, through the D-Bus API. At the moment,
|
|
device, swap, and target units are not supported at all as transient units, but
|
|
others are pretty well supported.
|
|
|
|
The lists below contain all settings currently available in unit files. The
|
|
ones currently available in transient units are prefixed with `✓`.
|
|
|
|
## Generic Unit Settings
|
|
|
|
Most generic unit settings are available for transient units.
