I added this to the Debian udev init script, run between mounting /dev
and starting udevtrigger.

mountpoint at least on Debian systems is part of sysvinit and happens to
be in /bin, but if /usr is available then you can as well use stat(1).

create_devroot_rule() {
  local udevroot=3D"$1"
  local rootnumbers=3D$(mountpoint -q -d / || true)
  local rootmajor=3D${rootnumbers%:*}
  local rootminor=3D${rootnumbers#*:}
  [ "$rootmajor" -a "$rootminor" ] || return 0

  echo 'ACTION=3D=3D"add", SUBSYSTEM=3D=3D"block", ENV{MAJOR}=3D=3D"'$rootm=
ajor'", ENV{MINOR}=3D=3D"'$rootminor'", SYMLINK+=3D"root"' > /dev/.udev/rul=
es.d/rules.d/61-dev-root-link.rules
}
