** Description changed:
+ SRU justification
+
+ Impact : Users of Precise cloud image on Azure cloud loose sudoers
+ identity when upgrading or doing a reconfiguration of the waliuxagent
+ package
+
+ Fix : Comment #4 outlines the changes made to fix the problem
+
+ Test Case :
+ - Create a 12.04 Precise instance on Azure
+ - run dpkg-reconfigure walinuxagent
+ - log out and log back int
+ User should be able to use 'sudo' to gain administrator's privileges from the user account defined when the instance was created.
+
+ Regression : None expected as no change in functionality only
+ packaging/installation modification were done.
+
+ Description of the problem :
+
walinxuagent, as packaged will result in a server losing its identity at
agent installation or at agent start. Specifically, it will remove
/var/lib/waagent (containing provisioning meta-data),
/etc/ssh/{config,ssh_rsa*} and /etc/sudoers.d/waagent. Because of the
way that Winodws Azure boots, this means that the identity of hosts will
be completely stripped out, the user who was provisioned with the system
will be locked out, and worst of all, a person who installs this package
on a non-Windows Azure system may be exposed to losing their host's SSH
identity.
