Well this problem I could solve. They were caused by an /etc/mtab
file which was out of sync, making mount -a believe some
filesystems were mounted when they weren't.
I have now a running setup. The only problem is that one has
to be root to do chroot in Fedora. So I created a user "sage"
inside the jail and start the notebook as follows
#/usr/sbin/chroot /sage-root su - sage -c "sage -notebook"
Are there any security problems associated with this?
