@nunigaia,You aren't right in case Openpli 4.0 - it boots from (USB) multiboot, but after reboot PLi did not see mounted HDD. Even after writing it to fstab by hand, HDD appears in mounts, but it is empty. In PLi's forum
@pr2 explained about this problem: "OpenPLi doesn't support MultiBoot, so it needs to be installed in flash."
Sorry, but i´m 100% right. I can boot OpenPli installed in OpenMultiboot. I can't boot Backed up images, at least what i´ve tested (( with OpenMultiboot moded by Meo ( BlackHole 3.0.2F in Flash ) i can boot even backup images ).
Note: Everything changes from one day to other. I own a Duo2 STB, where i test images and plugins. For example as far i know, PLI don´t have RTL8188eu devices working and drivers, but i have tested and it works on OpenPli. I don´t care if anything is missed on OpenPli 4.0.
It's possible to handle OpenPli 4.0 image iin OpenMultiboot --> Yes --> My HDD is recognized and my USB ( where i have picons, lcd4linux weather picons ), works without issues.
Everything it will work as in other images --> I don't have time and don´t intend to give suport for other images, rather than BlackHole or OpenBH images.
Anyway, thanks for your information, and this, is just to let you know.
best regards
