What version of Rescue am I running?

Updated 24 Jul 2017:

Basic Debian stretch Kirkwood rootfs for most Kirwood plugs:

- tarball size: 188M
- install size: 488M
- The init system used in this rootfs is sysvinit . To boot with systemd, see note 2 below.
- Installed packages: nano, avahi, ntp, busybox-syslogd (log to RAM), htop, isc-dhcp-client, dialog, bzip2, nfs server/client, iperf, ethtool, sysvinit-core, sysvinit, and sysvinit-utils.
- see LED controls in /etc/rc.local, and /etc/init.d/halt
- see some useful aliases in /root/.profile
- root password: root

Download at Dropbox:

Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2

md5:
bf3d29569943875df348fb5ca03b348c

And remember to check the hash of what you download, as always.

Installation:

Installation can be done on any Linux box, with a fresh USB drive (SD card or HDD would work fine too).

Note: all steps below must be done while logging in as root user (not sudo). If you are not the root user then don't continue, because the rootfs will not work.

1. Format a new USB drive with a single Ext3 partition, and label it rootfs. If you are running the latest U-Boot for Kirkwood then you can use Ext4.

2. Mount the drive on a Linux box. cd to top level directory and extract it. It is assuming the USB drive is mounted at /media/sdb1
cd /media/sdb1
tar -xjf Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2

3. Adjust fstab (optional).

Edit /media/sdb1/etc/fstab entry for root device to match the rootfstype of your rootfstype if you use Ext4 or Ext2. However, you can keep it as is without problem in booting since the kernel will figure out which file system the rootfs was formatted.

LABEL=rootfs / ext3 noatime,errors=remount-ro 0 1

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

Please replace kirkwood-goflexnet.dtb below with the correct DTB name for your box (see the folder /media/sdb1/boot/dts for the exact spelling of your Kirkwood box name).

Generate the uImage with DTB embedded inside:
cd /media/sdb1/boot
cp -a zImage-4.12.1-kirkwood-tld-1 zImage.fdt
cat dts/kirkwood-goflexnet.dtb >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.12.1-kirkwood-tld-1 -d zImage.fdt uImage
sync

If your Linux box does not have mkimage, then install it

apt-get install u-boot-tools

5. Done. Take this USB rootfs to your plug and cold start. After booted into Debian, see Note1 and Note2 below. It is very important that you do Note1 steps to secure your box.

It is all commented out, so do I simply uncomment the 'segate dockstar' entry?
