# Note 1: The default startup script always exits with exit code 1 due 
# to a bug in the ntripcaster script.
# Note 2: no logs apart from startup logs are currently output to stdout.
# Note 3: setting the console_mode to 0/1/2 in ntripcaster.conf has no effect
# as the casterwatch script passes "-b" to the ntripdaemon (see line 18) 
# which sets info.console_mode equal to CONSOLE_BACKGROUND (after parsing 
# the config file) which is equivalent to setting console_mode to 3.
