Sorry if I have been unclear: I don't want to have different
installation trees in the lua cache, I want DIFFERENT LOCATIONS of the
lua cache to be merged. So that the cache for
	TEXMFDIST
	TEXMFMAIN
	TEXMFVAR
lies in /var/lib/texmf/luatexcache, and the cache for
	TEXMFHOME
lies in ~/.texmf-var/luatexcache.

And in ~/.texmf-var/luatexcache there is ONLY the cache for TEXMFHOME
and not for the others.

So users can add/remove files from TEXMFHOME and update their local
cache without fiddling with the system wide cache.

Do go conform with other texmf.cnf settings, for example something like
this:
	TEXMFSYSCACHE=/var/lib/texmf/luatexcache
	TEXMFCACHE=$HOME/.texmf-var/luatexcache
and luatex/context collects the stuff found in TEXMFSYSCACHE and
TEXMFCACHE. Same as with TEXMFVAR and TEXMFSYSVAR

Best wishes

Norbert
