grub-install in chroot
I've been following the instructions on installing a Debian GNU/Linux system  and
found an issue that was not completely covered: I could not run grub-install in chroot
because there are no /dev/hdX special files. So the command to be ran in chroot
should be run as like that outside the chroot:
grub-install --recheck --root-directory=/mnt/debinst /dev/hda
I found this hint here  and hope it may be useful.
PS: I'm not on the list so please CC me if you want me to see the reply.
