Upgrading to ESXi 4.1 from 4.0.

I recently needed to update an ESXi 4.0 host to ESXi 4.1. After discovering that the host update utility was not supported with ESXi 4.1, I resorted to my other option, the vSphere CLI.
Here's the session (on Windows 7 64bit):

 C:\Program Files (x86)\VMware\VMware vSphere CLI>bin\ --server my_server -b -i

The output:

 Please wait patch installation is in progress ...
 The update completed successfully, but the system needs to be rebooted for the changes to be effective.

Followed by a reboot:

 C:\Program Files (x86)\VMware\VMware vSphere CLI> bin\ --server my_server -o reboot

 Host my_server rebooted successfully.
