^^^^^^^^^ (Sorry I accidentally replaced it by '/usr/local' in the

Thank you for advices!
I've understood that we should avoid /usr/local.
And, choices for a tree-prefix where luarocks will install rocks are:
1) luarocks_tree=/usr/share/lua/luarocks
2) luarocks_tree=/usr/lib/lua/luarocks
3) luarocks_tree=/usr/libexec/lua/luarocks
And rocks will go:
${luarocks_tree}/bin
${luarocks_tree}/lib/lua/5.3
${luarocks_tree}/lib/lua/5.4
${luarocks_tree}/lib/luarocks/rocks-5.3/
${luarocks_tree}/lib/luarocks/rocks-5.4/
${luarocks_tree}/share/lua/5.3
${luarocks_tree}/share/lua/5.4
I don't know which is the best.
Current choice is still /usr/share/lua/luarocks [1].
