Re: Relax the prohibition of usage fchdir(2) to quit a chroot



IMHO, we should not implement this "feature". We should not introduce ways to avoid deliberate, well-thought-out security mechanisms.

The use-case itself is broken, in my opinion.

Thanks Marc,

Well, right the better word is 'add feature' and we would change the
discussion from 'don't touch anything' to 'let's add chroot
restrictions swappable in runtime, that's a cool feature opening
opportunities' and then to mind-storm ideas what and how to restrict.

In some other way we might end up with floating patches around ;-)

With kind regards.
