So, actually, this bit is not true.
/usr/share/initramfs-tools/hooks/nbd looks like this:
-----8<-----
#!/bin/sh
# We don't have any prerequirements
case $1 in
prereqs)
exit 0
;;
esac
. /usr/share/initramfs-tools/hook-functions
manual_add_modules nbd
auto_add_modules net
copy_exec /sbin/nbd-client /sbin
----->8-----
The "copy_exec" in there is a shell function, defined in the
/usr/share/initramfs-tools/hook-functions library, which copies a
program *and all the libraries it requires* into the initramfs.
I checked, and on my system the initramfs does in fact contain all the
necessary libraries. You can check yourself; for instance, to check
libnettle you would do:
wouter@pc220518:~/scratch$ lsinitramfs /boot/initrd.img-$(uname -r)|grep
libnettle
usr/lib/x86_64-linux-gnu/libnettle.so.8
usr/lib/x86_64-linux-gnu/libnettle.so.8.6
or for gnutls:
wouter@pc220518:~/scratch$ lsinitramfs /boot/initrd.img-$(uname -r)|grep gnutls
usr/lib/x86_64-linux-gnu/libgnutls.so.30
usr/lib/x86_64-linux-gnu/libgnutls.so.30.34.3
If this doesn't work for you for some reason, then either you have
misconfigured initramfs-tools or something else is going on -- but at
any rate it is not a problem in nbd-client.
I'm leaving this open for the time being in case I missed something; but
unless you can show me that something is going wrong in the nbd-client
package, I'm going to close this bug a few weeks from now.
Thanks,

I will have a Tin-Actinium-Potassium mixture, thanks.
