2 title: What settings are currently available for transient units?
5 # What settings are currently available for transient units?
7 Our intention is to make all settings that are available as unit file settings
8 also available for transient units, through the D-Bus API. At the moment,
9 device, swap, and target units are not supported at all as transient units, but
10 others are pretty well supported.
12 The lists below contain all settings currently available in unit files. The
13 ones currently available in transient units are prefixed with `✓`.
