RHEL AS4 默认的运行级别是 5 ，如何在启动时不显示 RHGB ？
/etc/rc.sysinit 会检查 /etc/sysconfig/init 中的 GRAPHICAL 的值，如果为 yes，则启动 Rhgb-client ，如果设置为 no 则不显示（也就是 rh9 那样的模式）
[root@dhcp httpd]# cat /etc/sysconfig/init
# color => new RH6.0 bootup
# verbose => old-style bootup
# anything else => new style bootup without ANSI colors or positioning
BOOTUP=color
# Turn on graphical boot
GRAPHICAL=yes
# column to start "[ OK ]" label in
RES_COL=60
# terminal sequence to move to that column. You could change this
# to something like "tput hpa ${RES_COL}" if your terminal supports it
MOVE_TO_COL="echo -en \\033[${RES_COL}G"
# terminal sequence to set color to a 'success' color (currently: green)
SETCOLOR_SUCCESS="echo -en \\033[0;32m"
# terminal sequence to set color to a 'failure' color (currently: red)
SETCOLOR_FAILURE="echo -en \\033[0;31m"
# terminal sequence to set color to a 'warning' color (currently: yellow)
SETCOLOR_WARNING="echo -en \\033[0;33m"
# terminal sequence to reset to the default color.
SETCOLOR_NORMAL="echo -en \\033[0;39m"
# default kernel loglevel on boot (syslog will reset this)
LOGLEVEL=3
# Set to anything other than 'no' to allow hotkey interactive startup...
PROMPT=yes
