Speak, O Guru: How can I become a Unix Wizard?
O, Nobly Born: know that the Way to Wizardhood is long, and winding, and Fraught with Risks. Thou must Attune thyself with the Source, attaining the arcane Knowledge and Conversation of the System Libraries and Internals. Yea; and such an all-consuming Time and Energy Sink is this as to greatly Imperil thy Grade Point Average (if one thou hast), not to mention thy Sex Life (if one thou hast). But persevere, oh Larval One; rewards beyond the Dreams of Lusers await thee!
Speak, O Guru: What books should I study? Are the O'Reilly "Nutshell" guides a good place to start?
O, Nobly Born: know that the Nutshell Guides are but the outermost Portal of the True Enlightenment. Worthy are they (and praise to the Name of O'Reilly, whose books show forth the Hacker Spirit in numerous pleasing ways), but the Nutshell Guides are only the Beginning of the Road.
If thou desirest with True Desire to tread the Path of Wizardly Wisdom, first
learn the elementary Postures of Kernighan & Pike's
Immerse thyself, then, in the Pure Light of Maurice J. Bach's

These tomes shall instruct thy Left Brain in the Nature of the Unix System;
to Feed the other half of thy Head, O Nobly Born, embrace also the Lore of its
Nurture. Don Libes's and Sandy Ressler's

Speak, O Guru: To attain Mastery, how many Kernels do I need to take apart and reassemble?
O Nobly Born: this question reveals that indeed thou hast touched upon an Ineffable Truth about Unix --- that thou canst not Plumb its Mysteries by mere Study but must become One with it through Practice. The true Way to the Knowledge of the Source is not the timid and footling way of the Student, but the Divine Foolery of the Hacker. Hack, then; strive against Mighty Problems, have joy in thy Striving, and let the Crashes fall where they may (maintaining the while, for the Good of thy Karma, a Rigorous Backup Policy).
(In this wise shalt thou travel the Way of the Lion.)
In this day of Boot-Time Autoconfiguration and Dynamically Loadable Device Drivers, reassembling a Kernel is no longer the daunting Test and Seal of Mastery that once it was. However, writing and verifying thine own Device Driver for some piece of Exotic Hardware is still a worthy challenge to thy Budding Guruhood. Indeed, such Challenge may be found the Crafting of any Program sufficiently Powerful to Extend or Compete with the Tools now available in Open Source.
Therefore: seek thee out the Open Source Unixes: OpenBSD, FreeBSD, NetBSD, and most Especially Linux in any of its Incarnations. Join the Wizards and Aspirants to Wizardhood who Labor Unceasingly to Improve these. Commune with them in their Great Work, their unceasing Extension and Reinvention of Unix. In this wise may thou become one among the Mighty.
Speak, O Guru: Some there are who claim that the sole Path to Wizardry and the proper Way of every Right-Thinking Hacker is to rewrite the Unix Kernel from Scratch. Is this not Sacrilege?
Sacrilege, O Nobly Born? Nay! Certainly the Kernel Source is the Inmost Mystery of Unix --- but there is a Mystery beyond that Mystery. The Nature of Unix inhereth not in any one Version but in the Design Tradition of which all Unixes are Evolving Parts.
The Rite of the Rewrite is not the only Path to Mastery, but it is perhaps the highest and most Sacred of all Paths. Few indeed are those who, travelling it, have crossed the dark and yawning Abyss of Implementation to Delivery. Many, yea, many in truth stagnate yet in the Desert of Delay, or linger ever in the ghastly limbo called Perpetual Beta.
Speak, O Guru: What, then, is the True Path to Wizardhood?
O Nobly Born: learn, and seek within thyself. Cultivate the cunning of the Serpent and the courage of the Tiger; sup deeply from the Wisdom of those who came before thee. Hack, and hack again; grow, by trial and by error. Post thy best hacks to the Net and gain in Repute thereby. Also, O Nobly Born, be thou grave and courteous in thy speech; be helpful to those less than thee, quick to succour and slow to flame.
If thou dost these things faithfully, if thou travellest with high heart and pure intention, soon shall thy callow Newbiehood be shed. By degrees imperceptible to thyself shalt thou gain Power and Wisdom, Striving and Doing all the while. Gradually shall thy Puissance unfold and deepen.
O Nobly Born, if thou dost all these things, thy Wizardhood shall surely come upon thee; but not of a sudden, and not until after thy arrogant Mind hath more than half Forgotten that such was its Aim. For know this --- you may not by thyself in Pride claim the Mantle of Wizardry; that way lies only Bogosity without End.
Rather must you Become, and Become, and Become, until Hackers respect thy Power, and other Wizards hail thee as a Brother or Sister in Wisdom, and you wake up and realize that the Mantle hath lain unknown upon thy Shoulders since you knew not when.
(In this wise shalt thou travel the Way of the Child.)
