“I am writing a document for introducing system administration
in Linux, mostly with a beginner’s target. I have just released
several draft chapters in my home page at: http://members.xoom.com/rpragana/
(click at the word seminar in the “What’s new section”). The whole
thing is in Portuguese just now, but I would like to get some
translators to help me port it to English. It’s full of pictures
and has a different approach, more user-friendly in my opinion:
starts by teaching an easy to use tool before going to the “command
line”. Please check it out!”
