How-to chroot into Gentoo

• bzip2
• tar
• chroot
• stage3-ppc-uclibc-2005.0 (recommended for gentoo chroot) or stage3-ppc-uclibc-2006.1 (recommended for gentoo boot).
• portage

1. ln -s /mnt/HD_a2/bzip2 /mnt/HD_a2/bzcat
2. mkdir /mnt/HD_a2/gentoo
3. cd /mnt/HD_a2/gentoo
4. /mnt/HD_a2/bzcat stage3-ppc-uclibc-2005.0.tar.bz2 | /mnt/HD_a2/tar -xvpf -
5. cd /mnt/HD_a2/gentoo/usr
6. /mnt/HD_a2/bzcat portage-latest.tar.bz2 | /mnt/HD_a2/tar -xvf -
7. mount -o bind /dev /mnt/HD_a2/gentoo/dev
8. mount -t proc none /mnt/HD_a2/gentoo/proc
9. cp /etc/resolv.conf /mnt/HD_a2/gentoo/etc/
10. /mnt/HD_a2/chroot /mnt/HD_a2/gentoo /bin/bash
11. env-update && source /etc/profile
12. rc-update add net.eth0 default
13. rc-update add dropbear default
14. passwd root

If you did choose to use 2005.0 stage then you must update e2fsprogs!

net is needed only if you are going to boot gentoo using loader.o or flashed custom kernel.

wireless is needed only if you are going to boot gentoo using loader.o or flashed custom kernel.
Get new (1.1.0 BETA4) rt2500.o from here.

If you have exited from chroot environment after installing gentoo chroot or if you have rebooted your DSM-G600 then you need following commands to enter back in chroot environment.

1. mount -o bind /dev /mnt/HD_a2/gentoo/dev
2. mount -t proc none /mnt/HD_a2/gentoo/proc
3. /mnt/HD_a2/chroot /mnt/HD_a2/gentoo /bin/bash
