Bug#999695: systemd: emergency/rescue targets fail to stop journald

[westlake]

Package: systemd
Version: 247.3-6
Severity: normal

Upon booting up with "systemd.unit=emergency.target" to the kernel 
bootline, there are no systemd-journald services running.

However if the user boots normally into multi-user or graphical targets, 
and types "systemctl isolate emergency" or "systemctl emergency", debian 
does not stop systemd-journald services.

this is a problem noticeably if the user wants to perform work on "/" 
with "mount -o ro,remount /".

please fix this
thanks
