Due to installation challenges of OMV 5.x under Raspberry Pi OS Buster, I thought I give another try and reinstall OMV 4.x under Raspbian Stretch.
Are there any installation guides on how OMV 4.x can be installed under Raspbian Stretch? (The original OMV 4.x images are no longer available.)
I have found a pointer with the article titled Installing OMV 4.x under Raspbian Stretch on how the installation can be prepared and another note titled Installing OMV Extras for OMV4 under Raspbian Stretch on how the Extras can be installed.
Is there anything else that I may need to observe?
