关于grub.conf中rhgb quiet参数

先看一下我的grub.conf中的一段：

[marco.chan@linuxhobby ~]$ sudo cat /boot/grub/grub.conf
#以下仅为grub.conf的部分内容
title Fedora (2.6.27.21-170.2.56.fc10.i686)
root (hd0,1)
kernel /boot/vmlinuz-2.6.27.21-170.2.56.fc10.i686 ro root=UUID=0ed5871a-4675-4365-ab8c-375324900450 rhgb quiet
initrd /boot/initrd-2.6.27.21-170.2.56.fc10.i686.img
在上面的例子中，可以看到kernel后面有rhgb quiet字样。那具体表示什么意思呢？

rhgb表示redhat graphics boot，就是会看到图片来代替启动过程中显示的文本信息，这些信息在启动后用dmesg也可以看到。比如Fedora10，增加了此参数后，启动的时候看到进度条，不会再有文字启动信息了。个人建议：不要用此参数，让系统启动的明明白白。

quiet表示在启动过程中只有重要信息显示，比如说硬件自检之类的信息，启动界面中不再显示。

rhgb = redhat graphical boot – This is a GUI mode booting screen with most of the information hidden while the user sees a rotating activity icon spining and brief information as to what the computer is doing.

quiet = hides the majority of boot messages before rhgb starts. These are supposed to make the common user more comfortable. They get alarmed about seeing the kernel and initializing messages, so they hide them for their comfort.
