#2Can you configure it easily for a read only root file system?

#3Do you still have to have a canonical sso account just to login to your own devices?
EDIT: The answer appears to still be yes. I don't know who canonical is making this for, but no company is going to want to deploy IoT devices that hand over the root of trust for authentication to a third party. And I have to believe that many individuals/hobbyists that would otherwise be excited to use this will choose another distro for the same reason.
Canonical seems to be out of touch with what people actually want, and is happy to build things it likes that will ultimately be irrelevant.

#4Almost more interesting than this announcement by itself is that Canonical is now providing a PREEMPT_RT patched kernel for Ubuntu in general. That's super cool.

#5What IoT devices are running Ubuntu, and how is it optimized? That it has snap containers? I’m guessing by IoT here they don’t mean light switches running on an embedded processor, but industrial equipment?

#6I highly discourage anyone to use Ubuntu Core as part of their solution. It is a secure environment, yes, but it is a nightmare to configure (snaps) and for everything, expect for the most basic stuff, you will need what is called a "brand store", which costs about $20k/year, regardless if you have 1 or 100 devices.
(We could not even make one snap talk to another snap, checking another snap status etc).
We had commercial discussions w/ Canonical and we basically moved away.

#7This blog also mentions why Ubuntu Core is a bad choice.

They have no clue what the market wants. Nobody is going to shell out $15k-20k to build a solution.
We lost about 4 months betting on it and eventually moved away. We are glad we did.

#9For embedded / iot usage, one major issue is device support
https://ubuntu.com/certified/devices
It does contain raspberry pi's but the list isn't all that great.
I had trouble finding 32 bit ARM precompiled binary distributions from ubuntu (that is not a rpi), and had to compile my own kernel + inline it with debian to get 32 bit arm support.

#10For alternatives, I’ve been running opensuse microos in some test deployments and am really happy so far.
