A kernel panic? because of "missing libraries"? that doesn't sound
right. The kernel doesn't need "libraries".

iirc it's totally fine to unmount the backing fs after you mounted the
overlayfs, the file systems remain pinned in the background by the overlayfs.

You can extend the .mount unit file for /live/image and add an
explicit dep: i.e. create
/etc/systemd/system/live-image.mount.d/50-my-drop-in.conf, then add:

   [Unit]
   After=some-other.mount

You get the idea...
