[tex-live] luaotfload-tool writes database to TEXMFSYSVAR if writable

this is also a TeXLive issue in so far as it concerns
I have observed that doing "luaotfload-tool -fu -vvv"
puts its output in TEXMFSYSVAR if the corresponding
location is writable by the account issuing the command
For example on a test with user XXX I have
and I see on doing luaotfload -fu -vvv for user
XXX who actually owns 2016b/texmf-var
luaotfload | db : Gzip: /usr/local/texlive/2016b/texmf-var/luatex-cache/generic/names/luaotfload-names.lua.gz
luaotfload | db : Byte: /usr/local/texlive/2016b/texmf-var/luatex-cache/generic/names/luaotfload-names.luc
With user YYY, which has only read-access I get the expected
luaotfload | db : Gzip: /Users/YYY/.texlive2016b/texmf-var/luatex-cache/generic/names/luaotfload-names.lua.gz
luaotfload | db : Byte: /Users/YYY/.texlive2016b/texmf-var/luatex-cache/generic/names/luaotfload-names.luc
but if I open write access to YYY for repertory 2016b/texmf-var,
for example because
both YYY and XXX are in admin group, and I change the group
to admin for all of 2016b/texmf-var, then the invocation of
luaotfload by user YYY will produce the database in the
/usr/local/texlive/2016b/texmf-var repertory as it was for
XXX who actually owned the repertory.
This looks wrong because each user may have its own fonts,
and it is not because one user has write-access to
that it should mean that its personal config has to be made
I expect that account ZZZ with no write access will have LuaLaTeX
but there is an issue if both accounts XXX and YYY with write access
to /usr/local/texlive/2016b/texmf-var exist, and have no .texlive2016b/texmf-var
then XXX font config will overwrite the YYY one and vice versa.
My question to TeXLive generally is: is this behaviour of luaotfload
the expected one, are executables expected to write to the first
repertory where they have write access ?
otherwise stated, it seems luaotfload acts a bit like a luaotfload-sys
would. Is this normal ?
I will open a ticket only if needed on luaotfload github repo
depending on answers received here.
