The supervise-env directory

echo VALUE > /package/admin/svclean-conf/supervise-env/NAME

The supervise-env directory can be used to configure supervise's environment: run svclean-svscan with the $SUPERVISE_ENV environment variable set to the full path to this directory. This directory will then be used with envdir to configure supervise's environment. This lets you specify global values for $PATH, $DNSCACHEIP, etc. After changing any of these, you can put the change to use just by "svc -dx /service/foo". svscan will restart supervise with the new environment, so there's no need to reboot.
