No Space Left on Device – ESXi Patching

Encountered a new error that I have not seen before working with ESXi 6.5.  I was upgrading from the base VMUG ESXi 6.5 image to the latest patched and received the following error

[InstallationError]
[Errno 28] No space left on device
vibs = VMware_locker_tools-light_6.5.0-1.33.7273056
Please refer to the log file for more details.

The datastore had plenty of space left, over fifty gigabytes.  The fix is rather simple, but intuitive, enable Swap on a Datastore.  Simply set the Datastore attribute to one of your datastores and try the upgrade again.

Update Result
Message: The update completed successfully, but the system needs to be reboot ed for the changes to be effective.
Reboot Required: true

Hopefully this saves some people some time and aggravation searching around for answers.
