Pach has been submitted upstream: http://marc.info/?l=util-linux-ng&m=141184467317500&w=2 To repeat the problem: terminal 1$ sudo su - terminal 1$ echo $$ terminal 2$ kill -9 THE-PID-OF-THE-SU-IN-TERMINAL-1 It should only print "Killed", not "Killed (core dumped)" The patch may be slightly customized to avoid needing an extra internationalization for " (core dumped)", that is, with a leading " ". The patch just reorded the assignment of status, so it only changes the text print.
