The course materials were just the labs, along with succinct syntax
notes. Exercises were just "partition that drive according to the
following criteria", "create a PV/VG/LV that size", "build a level 1
RAID volume", "declare that RAID component invalid", that sort of
things. Theory was kept at a minimum and was orally exposed.

When managing educational efforts, I have encouraged instructors to
concentrate in hands-on training, write minimal labs guides, and take
the "Internet is already filled with info" approach wrt other docs. Of
course, guidance was given about where and what to read: look for docs
from your distro, learn to know when docs are out of date, etc.

My experience is that non-academia students, while enthusiastic, lack
studying muscle, and handouts you throw at them are seldom read or
understood. Face-to-face is different; that's the place where your
theory should go.

However, they can build up a practical understanding of the task they
must accomplish, so they can attempt to read documentation later. The
labs should pull the theory, while University does the other way
around. I found out this while being an instructor for Cisco CCNA
program -- it wasn't an easy switch.
