I know what the point of chroot is, (but note, according to http://www.bpfh.net/simes/computing/chroot-break.html it is possible to break out of a chroot jail, assuming you are root), if you'll notice in my original node I am planning on using chroot, my question was, why bother installing perl and so forth in my chroot directory? I plan on just chrooting my child process thats going to eval the untrusted code, that way I can leave the chroot directory completely empty.
