[luatex] How to avoid update of otfl-names.lua

[Yannis Haralambous]

Hi,

for the zebrackets system I have manually changed the otfl-names.lua file (all Latin Modern file names
have been replaced by those of the zebracketed ones). For example:

  {
   ["familyname"]="LMRoman17",
   ["filename"]={ "zebralmroman17-regular.otf", false },
   ["fontname"]="LMRoman17-Regular",
   ["fontstyle_name"]="Regular",
   ["fullname"]="LMRoman17-Regular",
   ["names"]={
    ["family"]="Latin Modern Roman",
    ["fullname"]="LM Roman 17 Regular",
    ["psname"]="LMRoman17-Regular",
    ["subfamily"]="Regular",
   },
   ["size"]={ 172, 240, 140 },
   ["slant"]=0,
   ["weight"]=400,
   ["width"]=5,
  },

This works perfectly (lualatex thinks it is using
Latin Modern Roman and in reality the font files embedded are those of the zebracketed version),
but *every time* I run a file, the font names database is updated anew: I get the message

luaotfload | Font names database loaded: /Users/yannis/.texlive2011/texmf-var/l
uatex-cache/generic/names/otfl-names.lua
luaotfload | Updating the font names database:
luaotfload | Scanning TEXMF fonts...
luaotfload | Scanning OS fonts...
luaotfload | Font names database saved: %s 
: /Users/yannis/.texlive2011/texmf-var/luatex-cache/generic/names/otfl-names.lua

This takes some time, and this is quite annoying. I wonder why the file has to be updated every time?
Has it to do with the timestamps at the end?

  ["zebralmroman17-regular.otf"]={
   ["index"]={ 212 },
   ["timestamp"]=1255129361,
  },

Since lmroman17-regular.otf has been replaced by zebralmroman17-regular.otf, I guess that the timestamp
is not correct, is this why the database is updated every time?

If yes, how are the timestamps calculated, so that I can recalculate them?

If not, is there some other reason?

thanks in advance

Yannis
