I'd vote against ENOPKG. That means: /* Package not installed */
A side-by-side error does not primarily mean that something is not 
installed.

My suggestion was not to propose EFAIL as an error message for a 
side-by-side error.
Not at all.
i should have made an extra toipic, actually, and if i would consider it 
important enough, i
would make one now.

What i meant was that sometimes i'm writing a program, and when 
searching for an
appropriate error code in errno.h, i don't find one. Then i would prefer 
to resort to some
genereric EFAIL.
Imagine a routine decodes an mp3 stream and fails because the mp3 data 
is corrupt.
What error code would match this? The best i found was:
    #define EBADMSG 77.     /* Trying to read unreadable message */

But i guess the solution would be to stay away from these more 
OS-centric error codes.

Again, i do not have a strong desire on discussing EFAIL, so we can stop 
here.
