Would you care to post more info? The fact that system `fstab` was ignored, and partitions were mounted into `/media/` as RO in loopback, would point towards `mkinitcpio` initializing your system as if it were a Live Image. Maybe you have `void-mklive` installed? Maybe there's some other hook at work? Weird. 

Anyway, I'm inclined to believe your problem with `mkinitcpio` was more of a mis-configuration case.
