Created attachment 100348

testing video on Arch Linux (with systemd v212)

Overview:
The 'quiet' kernel parameter has no effect during the latter part of shutdown
process.

Additional Information:
This may be a duplicate of this older bug: [0].
However the above one has been solved since systemd 206([1],[2]). And after
systemd 209, it seems that this bug appears again.
Today I tested this on Arch Linux(in virtualbox) with systemd 212.(gzipped webm
video as attachment)

Steps to Reproduce:
1.Ensure 'quiet' has been added to kernel parameter line, boot into OS without
any "[ ERROR ]" during the startup process.
2.login, then use 'halt' to shutdown.

Actual Results:
Several lines output without error message printed on screen by
systemd-shutdown.

Expected Results:
There are no output from systemd-shutdown(except the error output) when the
'quiet' appears on /proc/cmdline.
