How to reproduce:
Assuming artifact.mender with a valid rootfs image:
echo hola > dummy mender-artifact cp dummy artifact.mender:/non/existing/directory/dummy mender-artifact cat artifact.mender:/non/existing/directory/dummy failed to copy from: artifact.mender:/non/existing/directory/dummy to stdout: err: extFile: ReadError: debugfsCopyFile failed: file /non/existing/directory/dummy not found in image
For some unknown reason, I cannot reproduce the same issue in a unit test. See attached patch for a unit test with the same scenario; however the unit test does trigger an error on cp
