This analysis is correct. One could argue,that this is not a bug in
systemd but rather nfs-common, then again, the problem really is the
Debian specific patch which adds support for rcS type SysV init scripts.
Once we have converted all those to native .service files and we drop
rcS support, this issue should go away.
