Those 3 points should be fixed or at least enhanced with the set of 
patches I'm attaching now. Please look in particular on the 02 one as I 
changed back some errors values introduced by your recent commits (I'm 
unsure if that was just an oversight). I tried to rationalize the log 
erroring to be more coherent (and especially avoiding double erroring), 
hope this is what you wanted.

I didn't touch to the communication (and so, global flow) from 
systemd-fsck to systemd-fsckd point yet as changing it raises quite some 
issues as discussed in the other part of the thread (how to ensure the 
unit instance is in error if fsck fails or is cancel? How to even send 
the cancel message request itself if we don't have any communication back?)

Feel free to point any mistake.
