I added "set -x" to the start of /usr/share/initramfs-tools/hook-
functions::dep_add_modules_mount() and after it failed I grabbed the
output from /var/log/apt/term.log:

The bug looks to be a missing $ symbol to denote the dev_node variable in the
second test:
# recheck device
if [ -z "$dev_node" ] || ! dev_node="$(readlink -f ${dev_node})" \
|| ! [ -b "$dev_node" ]; then
! dev_node="$(readlink -f ${dev_node})"
should, I think, be:
! $dev_node="$(readlink -f ${dev_node})"
