System Reboots/Crashes after Dell-System-Update on BIOS

I upgraded two R740s  with dell-system-updater yesterday and both rebooted themselves involuntarily. The command I used was:  “dsu -n”.  

From the logs I was able to find,  it rebooted during BIOS update portion:

/var/log/dell/updatepackage/log/support

/usr/libexec/dell_dup/Log.txt

I took another same model box and only upgraded its BIOS “dsu -c=BI”. And it rebooted itself during the process. Pasted details below

Now, how do we prevent DSU from rebooting the boxes? This looks like a bug in the DSU tool as the ‘--reboot’ flag has not been supplied and yet it’s rebooting it. Or at least write out a message that its going to be rebooting the box. 

“--reboot  Restarts system(s) automatically if updates demands it for completion”

Let me know if you need additional logs from my end to confirm the issue.
