Package: systemd Version: 228-2+b1 Severity: wishlist Rather than at poweroff just saying "a stop job is running for session c1 of user jidanni", you should also say what is the culprit behind all of this.
I.e., the message should also mention which package is involved. The user is helpless to find out what is the culprit and can only just sit there and stare in wonder. Or he needs to go through all the trouble to power back on his machine just to find the seven or so characters that compose the package to blame's name.
