I'll pull this one, and extend the more program to check for symbolic links, like cat does, as soon as I can. Currently, running more on the README file in the /home/user folder returns nothing, because it is a sym link.

I'll handle this.

I do not think handling symlinks in userspace is the right thing to do.
What is your opinion on resolving the symlinks in the kernel when opening files and adding the O_NOFOLLOW option to the open syscall.
