I'm wondering again it would be better for luarock to install into /usr/local tree.


If we choose /usr/share/lua/luarocks as a tree root for luarocks, 
the tree will be

/usr/share/lua/luarocks/bin
/usr/share/lua/luarocks/lib/lua/5.3 
/usr/share/lua/luarocks/lib/lua/5.4
/usr/share/lua/luarocks/lib/luarocks/rocks-5.3/
/usr/share/lua/luarocks/lib/luarocks/rocks-5.4/
/usr/share/lua/luarocks/share/lua/5.3
/usr/share/lua/luarocks/share/lua/5.4

and if we choose /usr/local, the tree will be

/usr/local/bin
/usr/local/lib/lua/5.3 
/usr/local/lib/lua/5.4
/usr/local/lib/luarocks/rocks-5.3/
/usr/local/lib/luarocks/rocks-5.4/
/usr/local/share/lua/5.3
/usr/local/share/lua/5.4

The latter seems more intuitive for me.
