Bug#916670: cryptsetup doesn't work in buster
I have the same problem (though note that the configure script does in
fact exit without an error despite printing the error to the console.
I have to use dpkg-reconfigure to reproduce the error. I assume my
system isn't bootable but I'm not eager to test this):
root@tweedle:~# dpkg-reconfigure initramfs-tools
update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools (0.133+deb10u1) ...
update-initramfs: Generating /boot/initrd.img-3.16.0-6-amd64
cryptsetup: ERROR: Couldn't resolve device rootfs
My /etc/mtab is indeed a symlink to /proc/self/mounts
