Hi Michal,

Thank you for giving Snappy a try. We are working with Microsoft to
provide a top experience with Snappy on Azure. There are a few pain
points that remain, that we are working through. But iteration is fast.
In fact, the feedback from users like you is incrediably valuable in
making the Snappy experience first class.

Other user name used in provisioning will be not provisioned into the VM (via metadata) from cloud platform to the VM. Even if You use #cloud-config via cloud-init (it works on standard Ubuntu images). You must use an 'ubuntu' user name. You also cannot create other user (via cloud-init or manually via adduser).
Right now, this is a limitation on Snappy. We hope that this restriction
will be lifted in the future. Cloud-init, which populates the user
credentials defaults to using the ubuntu user.
> 2. sudo snappy update crashes VM. I have not investigated what is going on VM, but after 'sudo snappy update' and 'sudo reboot' machine is not responding. I think it is related to user creation step on provisioning - it seems to user is not persistent and disappears on reboot after update. But I'm not sure about that.
Can you elaborate on this? I think that this may be an issue related to
partitions. I am working with Microsoft to get details.
> I'm not the snappy specialist so I cannot really help You with snappy investigation but I can help You with Azure. If You need a subscription for tests, just send me an information about that. I'm working a lot with Ubuntu and I must be ready to new wave of architecture - containers. So I'm testing Snappy and Docker. I'm involved into Azure platform development so I wish to help with making Snappy working well on Azure.
Please ping me on IRC (#utlemming). I am on the team that delivers
Snappy to Windows Azure. Like I said, we value your feedback --
especially the bad and the ugly -- as it helps us to improve. Azure,
while an amazing partner platform for Ubuntu is a bit difficult to debug
so issues may take a bit to clear.
