Indeed i have on my system:
cat /etc/luarocks/config.lua
rocks_trees = {
   home..[[/.luarocks]],
   [[/usr/local]]
}

(and a file named /etc/luarocks/config-5.1.lua with the same content).

Several ideas to solve this:
- stop assuming things and remove that postinstall script (both
mkdir/luarocks-admin calls)
  i believe this is the correct, "lua-style" solution
- do not create directory, but call make_manifest and do not fail
postinstall if no tree is found
- furthermore, add /etc/luarocks/config.lua with that above config

Any thoughts about this ?
