Let's turn this into a bug report so this can be tracked properly.

The issue being that /lib/init/vars.sh has been moved from initscripts
to sysvinit-utils.
sysvinit-utils got a Breaks/Replaces: initscripts (<< 2.88dsf-59.5) for
that.
On the other hand, the initscripts has got a dependency on
sysvinit-utils (>= 2.88dsf-59.5) to ensure /lib/init/vars.sh is available.

As mentioned, dropping the Breaks should break the loop.
