Turns out udev was not upgraded alongside systemd:

% apt-cache policy  udev
udev:
  Installed: 175-7.2
  Candidate: 175-7.2
  Version table:
     215-6 0
        200 http://http.debian.net/debian/ jessie/main i386 Packages
     204-14~bpo70+1 0
        300 http://http.debian.net/debian/ wheezy-backports/main i386 Packages
 *** 175-7.2 0
        990 http://http.debian.net/debian/ wheezy/main i386 Packages
        100 /var/lib/dpkg/status


The Depends from systemd to udev is not versioned. Maybe it should be?

FWIW, the command used was `apt-get install -t jessie systemd-sysv`
