[Bug 2113963] Re: breaks linu-restricted-modules build

[Julian Andres Klode]

The file format for these files is:

<hash><space><mode><path>

where

<mode> is either a space for text mode, or a * for binary mode.

This works fine in the first line, but second and more lines fail with
*, that is:

Creation works fine:

Bug description:
  Hi

  lrm build fails, or it's 'lrg' intermediate to be exact. It's used to
  build signed versions of the nvidia modules, and the failing part is
  doing:

  sha256sum -c SHA256SUMS
  nvidia-drm.ko: OK
  sha256sum: *nvidia-modeset.ko: No such file or directory
  *nvidia-modeset.ko: FAILED open or read
  sha256sum: *nvidia-peermem.ko: No such file or directory
  *nvidia-peermem.ko: FAILED open or read
  sha256sum: *nvidia-uvm.ko: No such file or directory
  *nvidia-uvm.ko: FAILED open or read
  sha256sum: *nvidia.ko: No such file or directory
  *nvidia.ko: FAILED open or read
  sha256sum: WARNING: 4 listed files could not be read

  so the first file is checked fine, but it claims the others aren't
  present, but they are

  reverting to gnu-coreutils fixed it:

  sha256sum -c SHA256SUMS                    
  nvidia-drm.ko: OK
  nvidia-modeset.ko: OK
  nvidia-peermem.ko: OK
  nvidia-uvm.ko: OK
  nvidia.ko: OK

  tested on questing chroot.
