** Description changed:
- Latest Cloud-init on Windows Azure fails to provision on Windows Azure
- due to incorrect import.
+ [SRU Justification]
+
+ [Explanation] SRU for 1292648 added the ability Cloud-init to format
+ ephemeral devices when a new ephemeral device was put into place. The
+ backport used util.* instead of futil.*.
+
+ [IMPACT] Cloud-init stack traces when attempting unmount a device that is not
mounted
+ Cloud-init tries to unmount the default ephemeral disk and uses "try/except"
method. Since the wrong util is used, it will stack trace, preventing users
from provisioning on Windows Azure.
+
+ [TEST-CASE]
+ 1. Build new image from scratch
+ 2. Boot, it should work with ephemeral mounted
+
+
+ Latest Cloud-init on Windows Azure fails to provision on Windows Azure due to
incorrect import.
