Bundling fails on rsync on (non-GCE) CentOS 6.5

[feoff3]

I'm trying to bundle up Cent OS 6.5 created inside Windows Azure to move it to GCE.

The bundle operation fails with

19:14:34 platform exclude list: (/etc/ssh/.host_key_regenerated, 0:0:0) (/dev, 0:1:0) (/proc, 0:1:0) (/run, 0:1:1) (/selinux, 0:0:0) (/tmp, 0:1:0) (/sys, 0:1:0) (/var/lib/google/per-instance, 0:1:0) (/var/lock, 0:1:1) (/var/log, 0:1:1) (/var/run, 0:1:1)

After searching forums, doing research, I've found the reason is SElinux forbidding to access temp files.

Stopping SELinux by

echo 0 > /selinux/enforce

fixed the issue.

The problem appeared on CentOS at Windows Azure but it can appear on GCE too if SELinux is on and configured to prevent reading from temp files.
Adding the note to README or even adding turning off selinux before running rsync will solve the issue.
