[Bug 1050351] Re: lxc-start-ephemeral suppresses command exit status

[Serge Hallyn]

** Description changed:

- lxc-start-ephemeral supports executing a command directly, but always
- exits 0 rather than using the command's status, causing errors to go
- unnoticed when used programmatically.
+ ====================================
+ SRU Justification:
+ 1. Impact: lxc-start-ephemeral return status does not reflect the return status of the command it executed.
+ 2. Development fix: when the child successfully starts, return its return value.
+ 3. Stable fix: same as development fix
+ 4. Test case:
+ 	1. sudo lxc-create -t ubuntu -n p1
+ 	2. sudo lxc-start-ephemeral -o p1 -- /bin/false
+ 	3. echo $? # - this should return 1, not 0.
+ 5. Regression potential: the change is convined to lxc-start-ephemeral, so any
+    regressions should not affect any other functionality.
+ ====================================
+ lxc-start-ephemeral supports executing a command directly, but always exits 0 rather than using the command's status, causing errors to go unnoticed when used programmatically.
