There was some consistency issues in URLs to LFS. For example, in
systemd revision the URL to LFS "General Network Configuration" points
to the sysv book, this can be really troubling to new readers.
Instead of fixing them one by one, merge conditional XML developed by
Pierre from LFS.
I hope the links to the LFS books work, my local server is organised differently.
