75           sessiond(8)) to spawn from the lttng-create(1) command.

82           Unix user’s LTTng runtime configuration.
83
84           This is where LTTng stores the name of the Unix user’s current
85           recording session between executions of lttng(1).  lttng-create(1)
86           and lttng-set-session(1) set the current recording session.
87
88       $LTTNG_HOME/lttng-traces
89           Default output directory of LTTng traces in local and snapshot
90           modes.
91
92           Override this path with the --output option of the lttng-create(1)
93           command.
94
95       $LTTNG_HOME/.lttng
96           Unix user’s LTTng runtime and configuration directory.
97
98       $LTTNG_HOME/.lttng/sessions
99           Default directory containing the Unix user’s saved recording
100           session configurations (see lttng-save(1) and lttng-load(1)).
101
102       /usr/local/etc/lttng/sessions
103           Directory containing the system-wide saved recording session
104           configurations (see lttng-save(1) and lttng-load(1)).

107           $LTTNG_HOME defaults to the value of the HOME environment variable.
