Re: [vserver] [Grsec] audit denies pivot_root ?

Hi Rik

Just ran into this myself using the latest grsec+vs patch (30/12/2010
ish?). I had forgotten about this thread and gradually turned off all
the chroot restrictions and finally the audit_mount option before I
could start the vserver without the pivot_root error message... Very odd...

To be honest, I don't really have any incentive to debug this too much
further, so this is mostly a "me too". I guess I should tell the grsec
folks since it feels like it might be a bug there...

Thanks for continuing to bump the patchset!
