They install rocks into an alternative tree /var/lib/lua-site/.
That looks wrong to me, I'd have expected
/usr/share/lua/luarocks
or maybe /usr/local as a prefix depending on how much emphasis you want
to put on the user-installable part. The /var/lib tree is for local
state information per FHS, not installed components.
Thank you for review.
I've fixed it, so that luarocks should install rocks into
/usr/share/lua/luarocks, and updated packages [1].
^^^^^^^^^ (Sorry I accidentally replaced it by '/usr/local' in the
original mail: it is still /usr/share/lua/luarocks )
I'm wondering again it would be better for luarock to install into /usr/local
tree.
usually installation with a similar subtree are installed
under usr/lib
$ find /usr/lib -name bin
there are few cases under usr/share
but usually are sub-sub trees
$ find /usr/share -name bin
we have nothing "current" installed under usr/local
at all. No package should be installed there
Indeed - that's where I stash all my personal Cygwin scripts and exes.
Another good spot is /usr/libexec/ which is well populated by the likes of
git plumbing and other packages. I prefer the packages that populate
subdirectories rather than littering the top level like geoclue and gvfsd.
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].

Packaging luarocks varies across distros. Where I have been able to find target
directories suggests:
basing off Fedora as much here does:
https://src.fedoraproject.org/rpms/luarocks/blob/rawhide/f/luarocks.spec#_57:
mkdir -p %{buildroot}%{_prefix}/lib/luarocks/rocks-%{lua_version}
would suggest /usr/lib/luarocks/rocks-%{lua_version}
msys2 uses:
https://github.com/msys2/MINGW-packages/blob/fbe23378fcb1fa50dcd132ce8ab24217a6d9e433/mingw-w64-lua-luarocks/luarocks-x86_64.install#L8
${MINGW_PREFIX}/share/lua/5.1/luarocks/site_config.lua
/usr/share/lua/$VER/luarocks/
Arch uses:
https://archlinux.org/packages/community/any/luarocks/
usr/share/lua/$VER/luarocks/
slack uses:
https://slackbuilds.org/slackbuilds/14.2/development/luarocks/luarocks.SlackBuild#77
suggests /usr/lib{,64}/ and whatever make install defaults to.
Ubuntu uses:
https://packages.ubuntu.com/groovy/all/luarocks/filelist
/usr/share/lua/$VER/luarocks/
