Despite RH, the correct name (as defined by grub's author) for grub's 
menu is menu.lst, and it's generally found at /boot/grub/menu.lst - even 
on RH systems.

menu.lst isn't really shareable between different installations of 
Linux, and while it might work sometimes, the results ar unreliable: 
just imagine RHEL5 WS and RHEL Server sharing /boot.

Note that /etc/grub.conf is a symlink to the real menu and the real menu 
is usually on another filesystem.
