Comment 4 for bug 1684239

Thank you Rolando for your report!
I think the issue is valid and a backport as SRU [1] possible.

I don't think you need to upload further Data, yet there is more you can help with.
For the SRU and testing it we will need some simplified steps to reproduce (and verify the fix).
Also see the Section SRU Template in [1].

So if you could add your steps to create the vfat image that then lets you trigger this that might help - I doubt it in this particular case, but sometimes suboptions on those steps are important so it is always better to get those from the bug reporter.

Also - if possible - it would be great if you could verify that those steps on Yakkety or later then succeed as expected since the upstream fix is already in there.
