That seems like a good idea.

I'm not aware that there are any of those.

I'm afraid I'm unlikely to implement the proposed structured logging in
time for jessie, and the installer would need some work to make use of
structured log data.  However the firmware core code is already patched
so that it logs all failure in a consistent format that you can grep

"firmware: failed to load %s (%d)"

The parameters are the filename and negative error code; usually that
will be -ENOENT == -2.

The program is absolutely right; therefore, the computer must be wrong.
