What is Kernel boot quiet mode parameter?

This config file can be found under /boot/grub/grub.conf. I'm wondering what is quiet mean in this config file.

kernel /vmlinuz-2.6.32-71.29.1.el6.i686 ro root=UUID=977d4c1d-6127-409f-b53a-694c17e13d90 
rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM 
LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us     
crashkernel=auto LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc 
KEYTABLE=us quiet biosdevname=eth0 usbcore.autosuspend=-1

I search around the internet but I couldn't find any good resources explaining about this parameter.

Solution

  • If you are referring to a kernel boot parameter of quiet, then that is to disable most log messages.

    Linux kernel boot parameters.
