Did anybody managed to create a Squashfs OMV image for BerryBoot? It seems to me that could be one of most convenient way to use stand allone OMV for Raspberry Pi. You can really leave boot sector (BeryBoot) on SD card, and move OMV to HDD for betters speed and less wear-out.
There are manuals on that, but as far as I am not a Linux guru at all, I stopped in conversion process due to reason, that latest image for Pi consists of 3 parts, and I don't know which is essential.
Maybe some good guy (who knows the rules of Linux game) could help and convert latest OMV image for Pi 2 to Squashfs format? And put somewhere on an internet?
