Usage: $me [OPTION] PATH
This command starts supervisord with a provided configuration and set of
services in foreground mode. When the configuration changes, supervisord and all
services need to be restarted.
To do more efficient (but stateful) upgrades, use
\`nixproc-supervisord-switch'.
Options:
--state-dir Changes the directory in which the state of the
processes are stored
--runtime-dir Changes the directory in which the PID files are stored
--log-dir Changes the directory in which the log files are stored
--tmp-dir Changes the directory in which temp files are stored
--cache-dir Changes the directory in which cache files are stored
--spool-dir Changes the directory in which spool files are stored
--lock-dir Changes the directory in which lock files are stored
--lib-dir Changes the directory in which state files are stored
--force-disable-user-change
Forces to not create users, groups or change user
permissions
--show-trace Shows a trace of the output
--extra-params=PARAMS
A string with an attribute set in the Nix expression
language propagating extra parameters to the input models
-h, --help Shows the usage of this command
Environment:
NIXPROC_STATE_DIR Changes the directory in which the state of the
processes is stored
NIXPROC_RUNTIME_DIR Changes the directory in which the PID files are stored
NIXPROC_LOG_DIR Changes the directory in which log files are stored
NIXPROC_TMP_DIR Changes the directory in which temp files are stored
NIXPROC_CACHE_DIR Changes the directory in which cache files are stored
NIXPROC_SPOOL_DIR Changes the directory in which spool files are stored
