I believe that was filled as bug in installer long time ago.  I've read
somewhere somplace that it will be fixed in FC4 (maybe even FC3?), but never
bothered to check.  LILO worked fine for me on servers, so there was really
never a good incentive to switch to Grub.

To be fair, Grub offers some nice features.  For example, Grub doesn't require
reinstalling on config file update.  The question is how often do you change
config file?  If we exclude kernel installs, the answer is probably close to
never.  And if you use kernels from RPM packages, the postinstall script is
going to take care of that anyhow.

Another nice feature is that if Grub fails to load its config file (or 
boot the
OS), you still get CLI where you can attempt to boot by hand (LILO just gets
stuck).  After I reinstalled my laptop, this CLI is the only way I can boot it
(I already spent too much time attemting to fix it, the only thing I haven't
did was to reinstall LILO).  On the other hand, the previous installation used
LILO which booted the laptop every time.  Somehow I'd rather have boot loader
simply do its job, then offer me CLI to do it manually ;-)
