We don't install Ubuntu with FAI anymore, but when we did, I fixed this
using a hook for class UBUNTU (instsoft.UBUNTU):

# fix for /var/{run,lock} not being there at initrd-time
if cut -f2 -d' ' /proc/mounts  | grep -q ^$target/var$; then
    [ "$verbose" ] && echo "DEBUG: creating /var/{run,lock} on / (\$FAI${0##$FAI})"
    _varmoved=$(mktemp -d $target/var.XXXXXX)
    mount --move $target/var $_varmoved
    mkdir -p $target/var/run $target/var/lock
    mount --move $_varmoved $target/var
    unset _varmoved
fi

Jens.
