I don't really understand where the chroot comes into this but ... did you add the "-o /boot/grub2/grub.cfg" part? I forgot that bit a few times and then couldn't figure out why my changes weren't taking effect. :-) > Second, when running grub2-mkconfig from within my working gentoo > system, it fails with "error: failed to get canonical path of > /dev/root." which is apparently because I don't use an initramfs.
