- Experience. Unix has become to big for one to be an expert on
- all aspects and all flavors of Unix. Contrary to popular
- propaganda, the various flavors (AT&T, Sys V.3, Sys V.4, AIX,
- BSD, Ultrix, Mimix, Comix, etc) bear only a supreficial semblence
- to each other. It's also getting worse as features, intefaces,
- and enhancements are added. I consider myself fair at SCO Unix
- and Xenix. I just inherited an AIX customer and I am sweating blood.
-
- It is also hard to distinguish between sophistocated users,
- informed VARS, programmers, hardware types, and kernel hacks.
- Each would be considered a wiz within their area of expertise
- I've cleaned up many a Unix box from the debris left by experts
- far better versed than myself in the arcane arts of Unix
- internals but who have never had to keep customers and machines
- alive for extended periods. It's an art that must be learned
- by experience. Learn by destroying.
-
- >Which bibles should we study ? (after memorizing O'Rileys to become
- >an X Wizzie ?)
- You should not memorize anything. Half of what you know is going
- to be obsolete in about 5 years. It is more imporant to collect
- a list of names, phone numbers, email addresses, and such
- for those with specific expertise in areas that you expect to
- be involved. Then concentrate on the basics and understand how
- things operate. It is also handy to have access to as many machines
- as possible to compare configurations and reliability. A good
- collection of support bbs phone numbers are quite handy when you
- need answers at midnight.
-
- I strongly recommend buying and skimming (not memorizing) the
- various Nutshell books. They've saved my ass many times.
- Where you get the state of the art information (some of which
- is unfortunately wrong) are the magazines. I suggest:
- Unix World
- Open Systems Today (formerly Unix Today)
- Lan Technology
- The Guru (from the Valar Group Ltd)
- and others
- The official SCO documentation with Unix 3.2v4.x and ODT 2.0
- are radically better than the previous ugly grey incantations
- and are well worth reading. The really important stuff is in
- the release notes.
-
- >How many kernels (and which ones) we need to take apart and reassemble ?
- If kernel crunching is your forte, then as many as possible.
- However, if you neglect the other aspects of Unix configuration,
- kernel crunching is somewhat of a distraction. On an SCO system,
- I suggest you run:
- /usr/sys/conf/configure -x > filename (xenix only)
- /etc/conf/cf.d/configure -x > filename (unix only)
- and study the output. When you understand:
- What each kernel parmaeter does.
- What software it affects.
- What hardware affects it.
- Which packages change it's values.
- What diagnostics and monitor routines are available to optimize.
- What are reasonable values for common configurations.
- Why it's tweakable in the first place.
- then you can start dealing with internals.

- Maybe. To become a race car driver by building the race car
- and understand how everything works is helpful. However, methinks
- that first learning to drive the car would be more useful. Something
- like learning to walk before you can run. It is also helpful to
- own the car (or computer). There is no better incentive to learning
- Unix than keeping your own computer alive while your users and friends
- complain and/or demand changes.
-
- >So, oh, mylord, how does a mortal become a Unix Wizard ?
- Just add "Unix Wizard" to your .signature. Instant wizard.
-
- >(next question: how does a newbie become a net.personality ?)
- By spending inordinate amounts of valuable time replying to
- questions like this and posting the alleged answers to news.
- It also helps to be right so some research is helpful.
