with this code, failures of ldd should be handled

  ldd_output=$(ldd "${src}" 2>/dev/null) || return $?
  for x in $(echo "$ldd_output" | sed -e …)
  do
  done


the problem is when copy_exec is used to copy script files, for
example as cryptsetup does to copy the keyscripts

it can be solved in two ways:

1) check if ldd is running fine at the start of mkinitramfs
   ldd /bin/sh >/dev/null || exit $?

2) handle ldd errors and change packages to use copy_file instead of
   copy_exec when copying files other than binaries


ciao!
