I am installing CentOS 6.4 via a kick start file that looks like this in my build:# install the bootloader (GRUB)bootloader --location=mbr --driveorder=sda --append=crashkernel=autoAfter the installation I see this in /root/anaconda-ks.cfgbootloader --location=mbr --driveorder=sda --append=crashkernel=auto rhgb quietThe problem is I do not want 'quiet' appended the the kernel parms.  quiet gives the moving progress bar during the installation instead of the detail.  I want to see the details.Why does the installation add quiet to the bootloader when I never specified it??How do I prevent CentOS 6.4 from adding this automatically during installation???UPDATE:My initial post was wrong.. rhgb kernel parm enables graphical progress bar during boot.  So, in my case I needed to get rid of both rhgb and quiet.Updated my ks.cfg file and added suggested editing in the %post section.  Works great now!!!
CentOS 6.4 Kickstart bootloader problem
centos;kernel;boot loader;kickstart
According to the docs, it seems you can't get rid of it from Kickstart: http://fedoraproject.org/wiki/Anaconda/Kickstart#bootloaderBut what you can do is get the command line and the grub config replaced in the post-install (%post) section and delete it from there.I think this should do:%postsed -i -e 's/quiet//' /mnt/sysimage/boot/grub/menu.lst
