Hi Vasiliy, from what I read lowerdir, upperdir and workdir need to be directories, not devices. So how can you mount those three directories before setting up an overlayfs using them?
That should be possible with a couple of units injected into the initrd, but to me this seems more than what the fstab-generator can support at this time.
