Thanks Miklos,
I had tried that before, but that did not/does not work as well. The new
command (adjusted to my environment and from within the rescue-shell and
all within a single line) was:
# mount -t overlayfs overlayfs -o
lowerdir=/mnt/root_ro,upperdir=/mnt/root_rw,workdir=/mnt/root_rw/.work
/mnt/root

The new error message from dmesg now reads:
[ 1369.069178] overlayfs: workdir and upperdir must be separate subtrees

Thanks Klaus
