Lua in a sandboxed directory

[Thijs Koerselman <thijskoerselman@...>]

I'm using a modified version of the sandbox script Jim posted here:
http://snipt.net/jnwhiteh/install-lua-and-luarocks-into-a-sandboxed-directory/

I'm adding a path to LUA_PATH_DEFAULT in order for the sandboxed lua
to find my custom modules directory. This works well, but I noticed
that if the user has LUA_PATH set globally, in .bashrc or .profile or
something, things clash.

It there a way to have the sandboxed Lua ignore the standard LUA_PATH
variable? I would like it to be completely self contained and shielded
from any user/system variables. Is this possible?
