read & modify files out side chroot jail

Hello, I set up chroot jail on AIX system, the jailed user need to read and modify some files on the real system, for example lets say he need to edit /etc/hosts.

I was thinking of useing symbolic link "ln -s", but it doesnt work.

any Idea?

Wanting to modify system-owned files outside a jail doesn't match with the purpose of a jail (isolate processes). Why would you want to offer something like that anyway?

i want to create for example DB admin, but i dont wont him to have access to the system files, instead of changing permissions, it will be much easy and jail the user and just provide him with the application he suppose to manage.

I had been advised to use mount_nullfs and hard link "ln", so i will give it a shot.

Thanks
