Well, I do not have access to a N950 so I cannot say for sure, but Faenil promised to try it and report back to me.

I thought about that, and it is possible. Preparing the partition for ubiboot FS and copying the files there is trivial and even flashing the boot kernel can be done from the commandline, hence it's not difficult to make it into a deb.

However, I think this is pretty advanced stuff, making it into a clickable install packet might encourage people to try it without understanding WHAT they are doing. Especially as you need to tune the "/etc/boot.conf" according to your available kernels. This way at least you need just a bit of command line knowledge to install it.
