LFS101x as Optional Pre-Requisite for LFS201
Just recently purchased the LFS201+LFCS exam bundle for a great price and now starting to go through the course. I've stumbled that they are recommending the go through LFS101x before starting LFS201 as it has great tips on some topics not covered in detail on 201.
Is this worth the effort? I'm a fairly experience Linux systems admin (more than 10 years of use) but I have to admit some of the topics in 101x are not that familiar to me. Is it work the effort?
