That's what I thought.

But not in a state which would ever be suitable for applying to a
package.

I think I can rely on the systemd maintainers to reassign such bugs.

The release notes are available before a system upgrade.  If you have
apt-listchanges installed (it's installed by default) then NEWS will
be presented at a point when you can still abort the upgrade.

I suspect that you missed this during the upgrade to jessie, but things
just happened to work (with systemd mounting /usr later) until now.
