Hi Jan,
I do not have access to bug 1380175.
Can you tell me which build of RHEL-7.3 this fix is targeted for?

It's a 7.4 blocker, but has already been fixed in 7.2.
Comment 5 Jan Synacek 2016-10-18 07:33:35 UTC 
And the build is systemd-219-30.el7_3.1.
Comment 6 Sujith 2016-10-20 06:01:57 UTC 
RHEL-7.3-RC-2 does not have this fix since its having older 
systemd-219-30.el7.

Will it be included in RHEL-7.3-GA or RHEL-7.3 z-stream?
