Excellent course. I wish there was more time on the security modules for a deeper dive.

Paul was an excellent teacher, and delivered the course well. The LVM and firewall portions were especially useful.

The deep technical knowledge and involvement of the instructor in the Linux community. The lessons and insight were invaluable to me, and mostly derived from use cases the instructor provided to give context for specific utilities, or to explain the history of how utilities came into existence. Also, the deep knowledge of where to go in the kernel for additional documentation was fantastic! Finding the right documents for the right technology I have to configure, has always been a challenge.
