Best way I ever found to learn how things really work under the hood is |
| 41 |
to build a Linux From Scratch and pay close attention to every single step. |
| 42 |
|
| 43 |
Not that you'd ever actually *use* that system - there's no sane package |
| 44 |
management for a start - but after building an LFS, the content of |
| 45 |
ebuilds in @system starts to make a lot more sense; you can see why some |
| 46 |
of the decisions in the profiles were made; and make.conf now appears in |
| 47 |
a whole new light. |
| 48 |
|
| 49 |
Then take the valuable lessons from LFS and apply them appropriately to |
| 50 |
using Gentoo. These things are tools and the best workmen are always |
| 51 |
very familiar with their tools as a co-ordinated whole (as opposed to a |
| 52 |
bunch of mish-mash stuff cluttering up a toolbox) |
