Package: initramfs-tools
Version: 0.130
Severity: minor

Dear Maintainer,

We're working on a minimalist build of a Debian derivative which doesn't
include bash, and we ran into an situation in which due to a human error
the system didn't have a working ldd. This wasn't detected during an
image build process as mkinitramfs happily ignored ldd not working
(while being present and being an executable), and proceeded creating
a broken initramfs. In hook-functions, copy_exec does the following:

    # Copy the dependant libraries
    for x in $(ldd "${src}" 2>/dev/null | sed -e …)
    do
    done

The return code of ldd is not handled at all. Should ldd fail for any
reason, this failure will be ignored.

I tried to write a patch, but I couldn't come up with an elegant
solution which would cover cases other than just a wrong hashbang in
ldd :)

Maybe something like https://www.spinics.net/lists/dash/msg00165.html
can be used, but it's up to you to introduce hacks like that into the
code.

Thanks in advance.

  Andrew
