Yeah, I just ran afoul of the grub-pc "no floppy" bug.

After a fight with the rescue disk, I managed to install the newer
version to the MBR.  I mounted /dev/sda1 as my root, did "mount -a" and
used "/usr/sbin/grub-install '(hd0)'".

Now it pauses and takes an age to show the menu.  Then it takes another
age to start booting the kernel.

Not only does lilo work, but it has documentation and howtos.  Searching
the web for help with grub is an exercise in frustration.  What was grub
supposed to bring us anyway?
