Yes, but still, both emerges may run while you work, so that's not |
33 |
wasted time, while on a new install, your machine is useless till you |
34 |
get all that you need running (that's the compilation time for X, an |
35 |
office suite, a window manager), and after that, you gotta transfer |
36 |
all your files and settings (that may be tedious), and all of this |
37 |
takes a time you could use to work... |

|

All I'm saying is that you really don't need to start from scratch, I |
40 |
personally find it more productive and fast (not to mention less |
41 |
boring) to prepare and transfer the whole install, and only configure |
42 |
the new hardware (that is part of a normal new install, so, you can't |
43 |
avoid that), instead of waiting for compilations to end so you can use |
44 |
packages on your new machine. Besides, I'm letting the official |
45 |
portage tool do its job... |
46 |
|

Anyway, it is MHO. In some cases, this may fail and a install from |
48 |
scratch is the only option left. But I never had this bad luck. |
