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, some unit types (socket, swap, path) are not supported at all via unit types, but most others are pretty well supported, with some notable omissions.

The lists below contain all settings currently available in unit files. The ones currently available in transient units are prefixed with ✓.

Generic Unit Settings

Only the most important generic unit settings are available for transient units.
