@cjwatson
thanks for clarifying this for me.
Indeed, when looking in the initramfs context I see this :
(initramfs) . /root/usr/bin/ldd /root/usr/bin/makedumpfile
linux-vdso.so.1 => (0x00007fff0f9ff000)
libdw.so.1 => not found
libelf.so.1 => not found
libz.so.1 => not found
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f419e171000)
/lib64/ld-linux-x86-64.so.2 (0x00007f419e514000)
So I've ran a new test by revoking both proposed patches and using the
following syntax in /usr/share/initramfs-tools/scripts/init-
bottom/0_kdump :

Using the LD_LIBRARY_PATH here does allow for the dynamically-linked
makedumpfile to work adequately.
So this confirms Colin's statement. I have yet to verify if this is the
best place to make use of the LD_LIBRARY_PATH and to make it more
generic.
So I will remove the previous patches and post the new one once ready.
Thanks Colin for steering me in this direction.
