This is done on any system, which uses dracut and systemd for a long time now.

As SUSE switched to dracut recently, it should be the same as on RHEL-7/Fedora

If /run/initramfs/shutdown exists and is executable,
/usr/lib/systemd/systemd-shutdown switches root to /run/initramfs/ and executes

The shutdown script umounts the old real root (after umounting
/oldroot/{proc,sys,run,dev}), then if the old real root was living on an
assembled device, like mdraid, the device is disassembled and waited for the
device to be clean.

and for example for mdraid:

This solved quite a lot of problems for unsynced raids.
