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="$1"
local rootnumbers=$(mountpoint -q -d / || true)
local rootmajor=${rootnumbers%:*}
local rootminor=${rootnumbers#*:}
[ "$rootmajor" -a "$rootminor" ] || return 0
echo 'ACTION=="add", SUBSYSTEM=="block", ENV{MAJOR}=="'$rootmajor'", ENV{MINOR}=="'$rootminor'", SYMLINK+="root"' > /dev/.udev/rules.d/rules.d/61-dev-root-link.rules
}

ciao,
Marco
