not that helpful. users can still use io.open("/etc/xxx", "r") to
read files they want.
even if io.open is removed (impossible), we can still use \input /etc/xxx.
so a bsd jail(8)-like solution is indispensable.
btw, virtual machine is also a nice solution. Since each time it down,
reinstall a minimal operating system (like bsd base system) plus a
full working ConTeXt minimals won't take more than 3 minutes (1.5
minute to reinstall the operating system, and 1.5 minute to rsync the
source).
