Comment 4 for bug 1602256

Unfortunately the fix did not help.

Output in the journal now has an extra line about creating a slice.

:~$ sudo journalctl --file /run/log/journal/<xxx>/system.journal

Likewise the coredump list is empty
:~$ sudo coredumpctl list /usr/sbin/asterisk
No coredumps found.

(asterisk is the Ubuntu package in Xenial)
