This is not enough if systemd-sysv is also installed, since
/lib/systemd/systemd then becomes quasi-essential - packages are free to
assume that /sbin/runlevel works even if only unpacked and use it in
their preinst scripts.

While aptitude has its own dependency resolver, the unpacking order is
determined by libapt-pkg AFAIK.

It probably needs to use Pre-Depends to ensure that it's working during
upgrades. Note that the same holds also for sysvinit-core, although it
is currently less likely to hit the bug (it has "Priority: required" and
does not exist in wheezy).
See also #702524 for a similar issue in gawk.
