chroot escape: not on NetBSD

[Thomas Klausner <wiz%NetBSD.org@localhost>]

I just stumbled over these slides from a chroot escape methods talk:

http://www.slideshare.net/phdays/chw00t-breaking-unices-chroot-solutions

On page 27 there's a table which method works where, and NetBSD 6.1.4
is the only one where none of the methods work at all.

Well done :)
