Just a minor point here.

I have 2 systems running lvm over raid0.

On one of them (non-systemd init unstable box, but with systemd and
udev 223-2 installed) there's no /bin/systemd-run:

	# which systemd-run
	/usr/bin/systemd-run

Hardly possible to use _before_ /usr (separate partition) is mounted.

On another system (stretch (104 upgraded, 0 newly installed, 0 to
remove and 141 not upgraded), uptime: 13:09:13 up 840 days, 23:13, 67
                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
users), the systemd package is not even installed.  udev 222-2 and
lvm2 2.02.111-2.2 are installed.

systemd-run is refered to in /lib/udev/rules.d/69-lvm-metad.rules:

	ACTION!="remove", ENV{LVM_PV_GONE}=="1", RUN+="/bin/systemd-run /sbin/lvm pvscan --cache $major:$minor", GOTO="lvm_end"
