1 Hi folks,
2
3 Please bear with me, even if this seems a little newbie-sh.

5 I have a perfectly running Gentoo AMD64 system, with XGL and all. Now
6 I've figured that I need to change my CFLAGS. It's some stupidity on my
7 part, please don't ask. So I guess I'll need to rebuild my entire
8 system.

10 Anyway, I have about 11GB free on the hard disk. I am thinking about
11 building binaries of all the installed packages on the system, keep
12 them burnt on a DVD. I'll back up my /etc. All my data partitions
13 and /home are on different partitions, so I don't see any need to back
14 them up. Also, I'll keep the 2006.0 minimal install CD handy. It does
15 support LVM right? What do I do with the stage tarballs? How can I make
16 a snapshot of this working system as a fallback? I remember something
17 about a Stage 4 in the forums a while ago.. I installed this system
18 well over a year ago with a Stage 1 tarball. Should I keep Stage 3
19 handy?
20
21 Is there anything else I should be worried about? Have I forgotten
22 something in case something goes wrong and I have to reinstall the
23 entire thing...
24
25 Another thing, I'll need to make an exact copy of this system, once
26 rebuilt, on a friend's laptop, albeit with a different partition setup.
27 My system has LVM setup, the laptop won't have that. What all needs to
28 be changed?

30 Sorry to ask so many question, I'm just worried about messing up the
31 fine system.. :/
