The 1000ths time: it has nothing to do with systemd, and it fails
today already in many setups, also with sysv.

I'm so tired of the silly bugs it creates, it's time to move forward
and tell the guys that this isn't supported in today's reality. If
they wan to do it, systemd will not be in their way, random stuff will
just fail, just like it fails randomly with udev rules since years.

LSB means nothing for many distros, and you can tell it wrong, but it
will not change anything.

What will happen is that /usr will be on the rootfs. :)
