# Make sure that PIDFILE points to the correct location,
# if you have changed the default location set in the
# wrapper configuration file.

# Paths
# Note that (percent)INSTALL_PATH and (percent)SYSTEM_java_io_tmpdir
# should have been replaced by the izpack installer.
# If you did not run the installer, replace them with the appropriate path.

# PORTABLE installation:
# Use the following instead.
#I2PTEMP="%INSTALL_PATH"

# Application
APP_NAME="i2p"
APP_LONG_NAME="I2P Service"

# Wrapper
WRAPPER_CMD="$I2P/i2psvc"
WRAPPER_CONF="$I2P/wrapper.config"

# Priority at which to run the wrapper.  See "man nice" for valid priorities.
#  nice is only used if a priority is specified.
PRIORITY=

# Location of the pid file.
PIDDIR="$I2PTEMP"

# If uncommented, causes the Wrapper to be shutdown using an anchor file.
#  When launched with the 'start' command, it will also ignore all INT and
#  TERM signals.
#IGNORE_SIGNALS=true

# If specified, the Wrapper will be run as the specified user when the 'start'
#  command is passed to this script.  When running with the 'console' command
#  the current user will be used.
# IMPORTANT - Make sure that the user has the required privileges to write
#  the PID file and wrapper.log files.  Failure to be able to write the log
#  file will cause the Wrapper to exit without any way to write out an error
#  message.
# NOTE - This will set the user which is used to run the Wrapper as well as
#  the JVM and is not useful in situations where a privileged resource or
#  port needs to be allocated prior to the user being changed.
