This is still rough and will get updated, but creating pull request to make it more visible for people to look at. Feedback is welcome :)

This is extremely well done. The graph looks good! 👍

The two things that I noticed while going through it are:

• Networking 1 - I doubt if the third ability; using iptables to open and close ports should be required-for-junior
• Maybe the first three abilities from 'Using Bash' should be required-for-junior

Also, how about we sit together for a while to come up with a bunch of assessment questions?

So I took IPTables out of networking 1.

I also split up disk management further into a "inspecting" node, for investigating/diagnosing problems and two disk management nodes, 1 for a basic setup (formatting/partitioning), one for going wild with devicemapper / RAID.

Similar for service management, split it up in the basic administering task and a more advanced 'defining your own services' node.

Added a 'performance debugging' node, and added a 'networked filesystems' node.

Finally added at least 1 resource to each topic.

EDIT: I may think of some assessment questions already for the 'required-for-junior' ones.

Nice work, very thorough. Just being nitpick here, can you make the ids in the same format as all others, separating words with hyphens?
