What questions do you have? I originally added it because it was a newer kernel than the Debian kernel. Since proxmox is basically the Ubuntu kernel with Debian userland, I knew adding it to OMV (which is Debian too) would be very good. I'm a big Ubuntu fan and the Ubuntu kernel gets you a newer, more stable kernel than the Debian backports kernel in my opinion.
That pretty much answers what I was thinking. Thank you for that.
