   5     running the commands has a non-writable home directory.
   6
   7 `LTTNG_MAN_BIN_PATH`::
   8     Absolute path to the man pager to use for viewing help information
   9     about LTTng commands (using linklttng:lttng-help(1) or
  10     `lttng COMMAND --help`).
  11
  12 `LTTNG_SESSION_CONFIG_XSD_PATH`::
  13     Path in which the `session.xsd` session configuration XML
  14     schema may be found.

  19 The genoption:--sessiond-path option has precedence over this
  20 environment variable.
  21
  22 Note that the linklttng:lttng-create(1) command can spawn an LTTng
  23 session daemon automatically if none is running. See
  24 linklttng:lttng-sessiond(8) for the environment variables influencing
  25 the execution of the session daemon.
