Hi @thedrjones,

Thanks a lot for yet another contribution!
This is a nice addition to Rockstor so I'm eager to see it merged; I only have a few minor comments/requests that are all related to the capitalization of the Rock-on name.

Hi @thedrjones,

First of all, please accept my apologies for taking so long in taking a look at your PR. I have now taken the time to properly test it in:

• Rockstor-4.0.9 running on x86_64
• Rockstor-4.0.9 running on Raspberry Pi4_Leap15.2
• Rockstor-4.0.9 running on Raspberry Pi4_Leap15.3

It behaves as expected so my only requests are related to the capitalization of the Rock-on name.
Once these changes are in, I'll test a final time to make sure all is still right and then I'll merge.

Thanks again, and sorry for such a delay.

[thedrjones]

Changes placed for you. No worries about delays.

All looks good to me.

@thedrjones ,

Thanks for the little changes, I tested them again and confirmed it still works as intended. I'm thus merging it now.

Thanks again for another contribution! I'll try to do another merge and then work on publishing and announcing all of that.

Cheers!
