you use an old luatools / luat-inp.lua; if a patch is needed, then it 
should go into

function input.identify_own()
     local instance = input.instance
     local ownpath = input.getownpath() or lfs.currentdir()
     local ie = instance.environment
     if ownpath then
         if input.env('SELFAUTOLOC')    == "" then os.env['SELFAUTOLOC'] 
    = file.collapse_path(ownpath) end
         if input.env('SELFAUTODIR')    == "" then os.env['SELFAUTODIR'] 
    = file.collapse_path(ownpath .. "/..") end
         if input.env('SELFAUTOPARENT') == "" then 
os.env['SELFAUTOPARENT'] = file.collapse_path(ownpath .. "/../..") end
     else
         input.verbose = true
         input.report("error: unable to locate ownpath")
         os.exit()
     end
     if input.env('TEXMFCNF') == "" then os.env['TEXMFCNF'] = 
input.cnfdefault end
     if input.env('TEXOS')    == "" then os.env['TEXOS']    = 
input.env('SELFAUTODIR') end
     if input.env('TEXROOT')  == "" then os.env['TEXROOT']  = 
input.env('SELFAUTOPARENT') end
     if input.verbose then
         for _,v in 
ipairs({"SELFAUTOLOC","SELFAUTODIR","SELFAUTOPARENT","TEXMFCNF"}) do
             input.report("variable %s set to %s",v,input.env(v) or 
"unknown")
         end
     end
     function input.identify_own() end
end

function input.identify_cnf()
     local instance = input.instance
     if #instance.cnffiles == 0 then
         -- fallback
         input.identify_own()
         -- the real search
         input.expand_variables()
         local t = input.split_path(input.env('TEXMFCNF'))
         t = input.aux.expanded_path(t)
         input.aux.expand_vars(t) -- redundant
         local function locate(filename,list)
             for _,v in ipairs(t) do
                 local texmfcnf = 
input.normalize_name(file.join(v,filename))
                 if lfs.isfile(texmfcnf) then
                     table.insert(list,texmfcnf)
                 end
             end
         end
         locate(input.luaname,instance.luafiles)
         locate(input.cnfname,instance.cnffiles)
     end
end
