Using elevator=noop in RHEL

Why do we use elevator=noop in /etc/grub.conf on RHEL, I believe that grub.conf file resides in /boot/grub.....So should elevator=noop be defined in /boot/grub/grub.conf and /etc/grub.conf is wrong...

gheistCommented:
/etc/grub.conf is correct place.
FHS says:
2. Programs necessary to arrange for the boot loader to be able to boot a file must be placed in /sbin.
Configuration files for boot loaders must be placed in /etc.
The GRUB bootloader reads its configurations file before booting, so that must be placed in /boot. However, it is a
configuration file, so should be in /etc. The answer here is a symbolic link such as /etc/grub/menu.lst ->
/boot/menu.lst.

elevator=noop is very bad RAID controllers have very bad sorting algorithms in firmware.
deadline somehow compensates that
