I have a problem installing a package using lua scripts in %post:

error: Failed dependencies:
rpmlib(BuiltinLuaScripts) <= 4.2.2-1 is needed by 
filesystem-2.1.9-3mdv2008.1.x86_64

So if trying to install the package with --nodeps:
rpm -Uvh --nodeps filesystem-2.1.9-3mdv2008.1.x86_64.rpm
warning: filesystem-2.1.9-3mdv2008.1.x86_64.rpm: Header V3 DSA signature:

%post script
rpm -qp --scripts filesystem-2.1.9-3mdv2008.1.x86_64.rpm
postinstall scriptlet (using <lua>):
function mkdir_missing(dir)
    if posix.stat(dir) == nil then
        posix.mkdir(dir)
    end
end

mkdir_missing("/mnt/disk")
mkdir_missing("/media/floppy")
mkdir_missing("/media/cdrom")
