I've got an annoying and super-paranoid user... grr... but he pays well enough.
Right now, when this user logs in, he's chroot-ed into /home/MrPissMeOff/ which has a bunch of directories such as /bin /lib /home etc. He's locked in this jail and can't get out... fine.
What he's worried about is that I as root can get in. Is it possible to set his /home/ (so actually /home/MrPissMeOff/home/) to a permission in such a way that not even root can read his files? So that ONLY the owner can view them?
I thought I read somewhere that this was possible... but to take it further, can I still delete his files and account if need-be?
I'll raise the points if this gets complicated.
