Good. This will avoid the step of switching to SSH everytime.

Thanks for the testing, we should be nearly done. One last thing that can fail is left.
That command is trying to change a tool's config file in the firmware but I disabled all "switch firmware to read-write" functions because I don't want my script to make any changes in stock firmware.
Will have to make a chroot (disguise the tools folder as the root folder) to have our tool find our config so it can work, for now I move that file in a folder we can write into.
Can you test again the one attached here?

Konsole (KDE's terminal) allows me to scrollback "infinite" lines from "screen" as it makes a temporary file. It's the only terminal application I know that offers this.

Here we go: (actually I would have expected this script to take way longer for being done.)
Btw:
Could you please point me to the easiest way for making a full backup of stock bootloader + firmware + env (everything) and restoring this data to another GoFlexNet device before converting it? So I could revert if needed. Could I actually flash the same backup data of the GFN I'm currently using on another GoFlexNet either? Because I got to give away the one I am currently fiddling on, but I have an older one for myself, but that one already an old version modified bootloader and rescue system on it.
Thanks :)

BTW, the only NAND area that's going to be written over is mtd0 where u-boot is. So stock FW rootfs will not be touched.

bobafetthotmail,
> Will have to make a chroot
I'm not sure I understand why would we need to chroot? the tools are static, and the only thing need to be written to / is /etc/fw_env.config?
One more thing I forgot to mention: we need to check if the user is root and bail out if s/he is not root.

Argh, I should not cowboy-code when I'm at work (forgot to add the code to make the new folder). Can you try again with this?

Yes, that config must be written to /etc/fw_env.config but I don't want have to deal with the firmware.
I don't want to have to care about specific firmware configurations in a multi-device installer system like this as I'd likely have to add hacks for many devices and any firmware update may make this a failure point.
Besides, we don't really need to change it at all as the stock firmware cannot be booted from new uboot anyway.
With a tiny chroot the tool will think that $TOOLS/etc/fw_env.config is /etc/fw_env.config, and everything will be fine regardless of how the firmware actually is. Theoretically.
The current busybox has chroot command already, I'll make some tests this evening.
It's not complicating my work nor annoying as asking people to do it by hand in a tutorial.
The script is executed by a machine after all, let's leverage this.
It's more annoying when a firmware change/difference breaks my script out of the blue and I have to troubleshoot stuff over a forum in inappropriate moments.
Btw, also the original script from jeff also had a large amount of code dealing with making a chroot to install debian from scratch, that I have removed. (for now at least)

A good point. I've not seen devices that give you non-root shells but that's a possibility.

Looking fine, without an HDD attached. I know the script doesn't change nvram, yet, but does it already write to the HDD? I'd have to cleanup a drive then.
And would you prefer USB oder SATA storage?
Edit1:
I decided to kill my already existing Debian installation, plugged the Transcend SSD and rebooted.
The script doesn't recognize the SATA drive, yet:

Edit2:
Attached a log using an unpartitioned USB storage (actually just an microSD card in an USB-SD-card reader as I got no USB flash drive left).
Using this USB drive, the script cancels with:

I'd like to note that all that
is not caused by my script trying to write anything, it's probably caused by the fdisk -l command I use to scan for disks.

If you give me the full log of another run with that SSD I'll try to figure out why it is not detected.
It should have detected all drives that were connected at boot, hotplugging Sata isn't working well on Kirkwoods.

no, my mistake again.
It's unbelievable, I have tested this on my devices and there it worked fine even with this mistake in it. :/
Yet another script. Sorry for the inconvenience.
Please run one on USB and one on Sata, if possible.

It's no problem. :)
I started the GFN with both drives plugged in this time.
Seems like a little regression:
Btw:
I first didn't read the title exactly and thought that the script would also install a rescue system(That's why I though of backin up all mtds). But of course that's not of priority now and an option for later. Also I would like to remind you, to maybe 'individualize' the system in the end. Honestly I don't exactly remember what this was about, but I read it here in forum and it must have been something like creating an own system certificate, SSH key or such.. :)

One thing I hate to do is design-by-committee. So I will wait until you think it is ready, and review it.
There is one point I feel should make: the script should stay as simple as what Jeff's orginal version, as much as possible. I know we try to improve things, but I can't imagine that will be much more complicate than that script.
Stock OS does not use fw_env.config so it is OK to write it to the root. But I see your point of not touching FW. Just a reminder not to add many more moving parts that could break.

Got home and did some testing on my side too, I screwed up the setup of the toolbox and the script was using system's tools, so the behaviour was erratic.
:/
Now it properly uses the toolbox (as it can no more fallback on system tools as you see in the errors above), and I found and fixed other things too, probably also the sata issue.
I also wrote a chroot function and here works fine, it's the "02" option.
It will first do a fw_printenv using the system's tool (so will print your envs)
Then it will do a fw_printenv from inside the chroot so it will use our config file, and in your case this should error out as you don't have uboot envs in that place.
can you please test 01 with both Sata and USB and 02 (once)?
>I first didn't read the title exactly and thought that the script would also install a rescue system
The current goal is just installing Debian and uboot without fuss on the longish list of supported kirkwood boxes, as the tutorial is a bit long and scares off people.
Bodhi's modern uboot is fire-and-forget, as long as you plug a storage device with first partition labeled "rootfs" and all files inside in the right place it will boot Debian from it automatically (also works with a RAID, if you follow my tutorial from the forum's "wiki" in bodhi's signature).
As long as you have access to a Linux PC you can prepare another rootfs device with it.
To install a proper rescue system we need a rescue system for all (most) boxes first. The current one based on emdebian is relatively limited, pretty large for the embedded storage size, and works for some devices only (pogoplugs I think).
The very long-term goal (mine) is to have the script also install pre-made OpenWRT/LEDE firmware as a fallback. OpenWRT/LEDE is a third party opensource linux distro targeting embedded devices, it is mostly known for routers, it currently supports some of the kirkwood boxes, but far from all.
Being targeted at devices with 8-16 MB of storage, it's very light and allows me to fit more or less everything you ever need (also webinterface and all) in the 256MB or so that most Kirkwood boxes have.
From my limited testing with my Zyxel NSA310, it's just a matter of adding to their project the settings for making the firmware images for each box in the right way with stuff they have already, and that's what I'd like to do next.
But I'm not a hardcore developer so it's not going to be fast.

Yeah I know, it's at the end of bodhi's tutorial I think. This has to be done by something else I think, even if I can chroot into the rootfs, the kernel in the stock firmware is too old to run the new programs in it.
That's a task for another simpler post-install script, also for setting buttons and lights and so on.

Well, I agree on it but I'll also say that I don't like to work on things in my free time then being told you don't want it made like that or that you use things you don't like just to not offend me or something.
So yeah, maybe not very in depth, but having some feedback from you would be nice.
It is already structured as it would be in its final form, more or less.

Main difference is that I'm enclosing more stuff in functions as it makes the whole thing more tidy and easier to read.
It may be a habit or personal style.

The point of using our own static toolbox was that I could take advantage of decent tools so I could do relatively advanced things without fear of issues.
That chroot trick is one of them, but I'm fine with dropping it if there are better options.
If you have a better idea to avoid writing to / while still using fw_printenv/setenv (recompile a hacked fw_printenv hardcoded to look where we need it to look without having a config anywhere?), I'm all ears.

Understood :) I've been a little bit too busy so willl try to review it and and test on a couple of my spare boxes (GFNet/Home) before the weekend is over.

I think that's the only way. If we don't chroot, we have to write to / to use fw_printenv/setenv after flashing envs image at 0xc00000. So I think chroot is cool to avoid messing with stock /.

Did you notice that it doesn't even download busybox at all?
We are still using stock wget at this point and you are trying to download through https.
Edit:
For saving us one post-cycle, I placed busybox onto my pc and changed the script to download busybox from there.
Results for both options (sata and usb) are in attachments.

Thanks for taking the time to do the hack to test further.
It seems the device does not have the drivers to mount ext4 partitions, not even as ext2, which was the "last thing that could have gone wrong" I was talking about (I was underestimating my own ability to cause trouble).
"mount: mounting /dev/sdb1 on /tmp/rootfs failed: Invalid argument" for both, and on a system that has ext4 driver it works fine.
This means I have to switch to plan B: using dd to write a small ext4 partition image with the rootfs inside, counting on e2fsck (file system checker) to expand that into a larger partition. I'm half sure it should work.
Or Plan C and use ext3 or XFS or even ext2 depending on what drivers the device has. ext filesystems are bootable for uboot, XFS is not so I would have to make a separate /boot partition.
Or Plan D and scrap the part of the script dealing with rootfs creation and simply make a dd image of the rootfs the users can write on a drive with Rufus (windows program to make bootable usb drives and similar) or whatever other tool from their PC and distribute it in a 7z archive so it is compressed and not as large as the partition it will create.
Any ideas? What would you prefer of the proposed solutions?

bobafetthotmail,
> Any ideas?
One foolproof solution would be reversing the installation. And we only need a small toolbox. Let's try creating the basic rootfs first using ext3, and then chroot into that and do u-boot installation.
The things to watch for if we doing this: we need to gather the mtds info, ethaddr, ... things that in the rootfs chroot we can't see.

What about first creating mini os, that after creation installs uboot, then reboots and self destructs for making place for the final installation?
Edit:
I have just seen, that there's a fuse module. So couldn't you load fuse-ext2? I read that it had experimental ext4 support.

Hmm, the current toolbox is smaller than a rootfs and should be able to install uboot fine already.
Here the issue is that it would be nice to have a ext4 rootfs even if stock firmware does not have that driver.
I don't know if the Debian Jessie (or later) applications in the chroot will run at all with the kernel 2.6 of stock firmware.
We can simply try to use ext3 for the rootfs without making changes to the script, but I'm not very happy with that compromise (and I'm sure there will be devices that lack a ext3 driver too).

Yeah, this would have been the plan A if we had a recovery to flash in the internal flash. Flash uboot and recovery while into stock firmware, reboot in recovery, install Debian from recovery, reboot to Debian.
In our case we can make it anyway with a usb drive. we format a ex2 partition as rootfs, install a tweaked rootfs in it, on reboot it calls automatically a script that finishes the installation then erases that usb drive.
---
I'll have to test if Plan B (as said above) works at all. If it works it would be faster than using a recovery drive as above.
In the meantime I've attached the script, hoping it does not break again, it should now try to make a ext3 rootfs instead of a ext4 rootfs. See if it works now

On the contrary, ext3 rootfs should be used, IMO. This has ramification: backward compatibility (see my instruction for installing rootfs). Ext4 is better no doubt, but it would prevent the user to ever boot with stock u-boot again. So I always leave it to the users to upgrade it later.
Upgrading from ext3 to ext4 is quite simple to do after the installation. I think it is best to leave the rootfs as ext3. Stock uboot/OS can use ext3, if there is no ext3 driver, it wil just simply use ext2 without the journal.

Hm, looked up the upgrade path to ext4 https://ext4.wiki.kernel.org/index.php/UpgradeToExt4
I have some doubts that this can be performed on a live rootfs, but iit's easy enough for me to do the switch from my linux PC.
To use the older uboot again we need to have also stock uboots somewhere, or we should hope that the place the script dumps the images to does not get erased (I'd rather like to send them to a ftp server so we can offer stock uboots + envs for various devices too).
So fine for me, ext3 rootfs will be then.

>(Regarding the ext4 problem: Did you see that there's a fuse module? I edited it in, but I think this was after you had posted on already.)
It's easier and less likely to blow up to just steal a ext4 kernel module from some ARM kernel 2.6 and modprobe it in with the script, but I'd rather avoid it as it is not guaranteed to work on all boxes.
---
also, added that --no-check-certificate to the script, now it should really work, hopefully.

Jeff copied the original u-boot to stock rootfs. But we are strict about messing with stock. So I would dump it to /tmp only (1MB or less). And then at the end, copy the image to the new Debian rootfs /boot.

And we got a winner! (for sata and usb)
PS:
Again for the backup question that I had:
I would like to clone the GFN I am currently working on to another one, for making the other one stock again. The other one is completely modded including rescue system. So that's why I need to backup more than mtd0. I could use the older GFN then for more testing with stock formware and such, but I have to mod and to give away the current one.
I also tested booting with the USB drive on one of the modded GFNs, it's working fine (besides that I cannot login Debian, because of 'Permission denied (publickey,password).').
I can't test booting the SATA drive, because of that latest problem there.

---everything fine Installation complete You can now reboot your device into Debian. If your device does not start Debian after rebooting, you may need to restart the device by disconnecting the power. The new root password is 'root' Please change it immediately after logging in. Reboot now? [Y/n]

Please post this as a different topic in u-boot forum (how to backup/restore your NAND patitions).
