On Ubuntu 20.04, I am trying to create hard links to some essential tools in /usr/bin for use inside a chroot jail. When I try, I get an "Operation not permitted" error. My current workaround is to copy the necessary files to my home directory, and then create links to them there whenever I construct the jail, but of course they won't get updated if the originals do.
Why is this happening, and is there any way around it?
