The nbd-client binary (/sbin/nbd-client), while working fine on the regular
system,
is not working inside initrd images (which have very limited set of libraries).
During system startup, it is failing with:
/sbin/nbd-client: error while loading shared libraries: libgnutls.so.30: cannot
open shared object file: No such file or directory
Currently the nbd-client used for building initrd images is copied the
initramfs hook
/usr/share/initramfs-tools/hooks/nbd
which uses the regular /sbin/nbd-client, which has the following dependencies
(the example is for i386, but, of course, similar for others):
# ldd /sbin/nbd-client
linux-gate.so.1 (0xb7f3f000)
libgnutls.so.30 => /lib/i386-linux-gnu/libgnutls.so.30 (0xb7cf5000)

(0xb7cec000)

libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb7679000)
which, as one can expect, are not met inside an initrd...
Obviously, initrd images require a different binary to function properly.
Currently such binary is not available in the deb package...
Also, the one from installer's nbd-client udeb package, doesn't work either
(it is missing libnl-genl-3).
Personally, I resolved the problem by building a custom version of the nbd-
client
from sources, with possibly minimal dependencies:
# ldd nbd-client
linux-gate.so.1 (0xb7f60000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb7d54000)
/lib/ld-linux.so.2 (0xb7f62000)
and changing the initramfs hook to use it.
