#
# Formating the boot script messages:
#   The boot scripts should use the variables rc_done and rc_fail to
#   symbolize their success.  See /sbin/init.d/skeleton for an example
#   how to use the shell function rc_status and rc_reset.
#   Internally these function uses the variables rc_done and rc_failed.
#   rc_done_up and rc_failed_up do the same as rc_done and rc_failed
#   but one line above (usefull for starting daemons who talk to user).
#   The variable rc_reset is used by the master resource control script
#   /sbin/init.d/rc to turn off all attributes and switch on the standard
#   character set.
#
#    \033          ascii ESCape
#    \033[<NUM>G   move to column <NUM> (linux console, xterm, not vt100)

#    \033[<NUM>D   move <NUM> columns backward but only upto first column
