Hey juiceme,
I thought I had already summarized above
But once again (maybe more precise).
Nit is working
Harmattan (all kernels) working
But yes, now that I read the thread back a bit I find all the information there.

Nemo:
I got it (this morning)
I had a wrong link (mnt/7 instead of /mnt/7). Please do NOT kill me (even remotely) ...
BUT: that was not enough. The return value of kexec -l was 255. So we never ever got to execute the kernel or return to console. Nice idea would here be to go back to menu?
So i just added a few lines to return a "0" in case the result was not "0". Then Nemo booted fine !? What the heck? I did not find meaning of "kexec -l" returning 255. But kexec -e worked.

So no problems at all with partitions or logical disks or my mods (just the wrong link).
Thank you
--edit
OK, got a dead battery. And put it to charger. Checked again and now return value is "0", so everything okay!
This time bootreason=usb. When I got the 255 the bootreason was sw_rst. Maybe this caused the 255? IDK.
But I am happy
I find it highly unlikely that this has something to do with the kexec_load return value.
Actually, this is just the indicator I need to watch for, as the bug correction mentioned earlier

--Remarks
- I still have sometimes weird restart behavior, i.e. after decoupling battery (nemo did not start) it needed a few attempts. It seems bootreason=pwr_off? Maybe change the bootreason in command_line also?
- Charging does not take place when connected charger to powered off phone. it goes to ubi console and does not charge.
Maybe wait for 60s and when there was no telnet connection established (do not know how to detect) then boot to Harmattan (bootreason=act_dead) and let it charge?
To be fixed in near future

It would not be too difficult to implement a small shell interface with something like it...

Seems I need to educate myself a bit more ...

toosa.swagman.org is down?
Thanks to your work I start to like the N9, even I still need a PC alongside

The charging/connection seems to be a tradeoff at the moment. It could be possible to hack up a module that does both, maybe. I really just took what was already there and did not look that deeply into it.
Re: toosa being down, no, it's up, but there's some DNS trickery going on, maybe?

Updated ubiboot to use alternate installation FS. Now it is possible to use either mtd4 or mtd5 partition.
See changes of installation the README file
