There are two ways to do it; either mount them multiple times (works for
virtual filing systems) or bind mount them into the new location (works
for anything). Bind mounts even work for files, so for /etc/mtab you could
do (assuming the new system is in /mnt/chroot):
# touch /mnt/chroot/etc/mtab
# mount /etc/mtab /mnt/chroot/etc/mtab --bind

It might also be instructive to work through the first stage of a Gentoo
install - I don't know if they do anything beyond bind mounting the
necessary bits but the first stage does all take place in a chroot and
IIRC involves building grub, so there must be a way to do it.
