Hi everyone I was hoping someone would have suggestion for me.
My hard drive was going bad so I bought a new one and put it in.
Instead of doing a complete reinstall I used dar and a usb harddrive
to do a backup of the system. I then used a gentoo live cd (2004.2 or
3) and to get everything setup and copied over. That worked well and
up until I had to chroot in and take care of the grub setup.
I keep getting glibc errors with "symbol erron" when I try to run
env-update, ls or emerge commands.
When I run grub root (hd0,0) it says no such drive or device. My
/dev/ folder in the chrooted environment is empty.
The system is a 2.6 kernel with 2.6 headers. I wonder if maybe I need
an updated cd.
Does anyone else have anymore ideas.
Thanks,
Andrew

A couple of more steps may be necessary before the chroot. Assuming
that your root is mounted on /mnt/root:
cd /mnt/root
mount --bind /dev dev
mount --bind /proc proc
mount --bind /sys sys
chroot ./ ./bin/bash
mount -a # only if /boot is a separate filesystem
grub-install /dev/hda
umount -a # only if /boot is a separate filesystem
exit
umount dev
umount proc
umount sys
cd ..
umount root
HTH,
-Richard

Thanks your reply helped me a lot. That was exactly what I needed.
It turns out there are important files in /dev/ that are not
dynamically generated.
Thanks again,
Andrew
