/storage will be unmounted by systemd-shutdown, like /flash.
As the squashfs root has several symlinks to /storage it
should not be unmounted during the normal shutdown process.
This prevents the symlinked files/directories vanishing too early
and also removes the "unmount /storage failed" messages when
netbooting.
Drop-ins for the storage mount unit didn't work before (due to a systemd bug in combination with the order in which we mount filesystems in initramfs), so include the proposed fix which should hopefully make it into the next systemd version.
