How-to chroot into Gentoo
Files needed
- stage3-ppc-uclibc-2005.0 (recommended for gentoo chroot) or stage3-ppc-uclibc-2006.1 (recommended for gentoo boot). Don't use 2008.0 stage because it is compiled against 2.6 kernel headers.
Installing steps

- Update /etc/conf.d/net
env-update && source /etc/profilerc-update add net.eth0 defaultrc-update add dropbear defaultpasswd root- If you did choose to use 2005.0 stage then you must update e2fsprogs!
emerge e2fsprogs - Always make sure that devfsd is installed!
emerge -pv devfsd - It is also recommended that you update sys-apps/baselayout package. Its needed by net configuration to change mac address. However, by default, baselayout pulls in and builds module-init-tools with support only for 2.6 kernels. So, to allow the updated module-init-tools to be built with support for both 2.4 and 2.6 kernels:
echo "sys-apps/module-init-tools old-linux" >> /etc/portage/package.use emerge sys-apps/baselayout
/etc/make.conf

chrooting
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.
mount -o bind /dev /mnt/HD_a2/gentoo/devmount -t proc none /mnt/HD_a2/gentoo/proc/mnt/HD_a2/chroot /mnt/HD_a2/gentoo /bin/bash
Chrooted DropBear
will fail by default due to the default kernel not supporting uni98 ptys.
Correct build:
EXTRA_ECONF=--disable-openpty emerge dropbear
First time installation:
ln -s /dev/urandom /dev/random mkdir /etc/dropbear/ /usr/bin/dropbearkey -t dss -f /etc/dropbear/dropbear_dss_host_key /usr/bin/dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key
Auto-start from fun_plug (assuming a working busybox):
ln -s /mnt/HD_a2/bin/busybox /bin/chroot ln -s /mnt/HD_a2/bin/busybox /bin/makedevs cd /dev /bin/makedevs ptyp c 2 0 0 9 /bin/makedevs ttyp c 3 0 0 9 ln -s urandom random mount -o bind /dev /mnt/HD_a2/gentoo/dev mount -t proc none /mnt/HD_a2/gentoo/proc cp /etc/resolv.conf /mnt/HD_a2/gentoo/etc/ /bin/chroot /mnt/HD_a2/gentoo /usr/sbin/dropbear

Troubleshooting
- If you can't get to the login then press ctrl+c right after /dev and sda3 is mounted.
- If your root file system is read-only then use
mount -t ext3 -o rw,remount /dev/sda3 /to get write access. - Current e2fsprogs 1.40.4 fails to build with following error:
../../lib/libuuid.so: undefined reference to `___tls_get_addr'See http://bugs.gentoo.org/show_bug.cgi?id=204102 for more details. Workaround is to use version 1.40.3 by runningecho '>=sys-fs/e2fsprogs-1.40.4' » /etc/portage/package.maskbefore emerging.
Installing an older package
Current version gentoo packages may not work on DSM-G600. If you gets Masked packages because of unsupported EAPI or package only support kernel 2.6, try to install an older package by browsing to /usr/portage/category/application or going to the CSV tree : http://sources.gentoo.org/viewcvs.py/gentoo-x86/ and searching older version of the package. Once the version found, install it with this command :
emerge -av =category/package-version
