Why FressDOS and FressBSD?  I assume it's typos.  Why isn't Linux
capitalized?  MS-DOS is written with a dash.  "Windows Vista bootmgr"
should be "Windows Vista" and "Windows NT/2000/XP loader" should be
"Windows NT/2000/XP".  It's not like we are just booting the loaders.

inird should be initrd.  Please add check for the Fedora style names for
initrd, namely "initrd-KVER.img".  Or maybe you just missed ".img" in
the second check?

The change to grub_lua_file_exist() is dubious.  It's not clear why the
requirement is that all files exist.  Maybe I don't know the style of
lua, but I think it's wrong to hardcode the AND logic just because one
script would benefit from it.

If we consider e.g. the wildcard expansion in make, it will return a
non-empty value if any file exists, i.e. the OR logic is used.

I suggest that you split the lua.mod changes and osdetect.lua.  The
later is obviously a bikeshed issue that can be discussed for a long
time.  The former needs a more technical consideration.
