bootstrapping after stage3 installation [solved]

[Specialized]

As I installed my Gentoo System, I was a absolute newbie to linux, so I did a Stage3 Installation.
Now I'm trying to optimize my System. I've tried to switch to the gcc-3.4 Compilers, but I always got Problems with my kernelmodules.
I thought maybe I can bootstrapp my System new to use the gcc-3.4 and switch to the pentium-m cflag and use pentuim m in my kernel .config instead of pentium 4.(I'm using a IBM t41p with centrino-processor)
Is this possible or do I crash my System instaed of improving it?

Many thanks for your answers!!!

Yes do that. First you might want to emerge gcc then you might want to emerge -e world twice (I heard this links everything right). Also I think that you can safely use -O3 in your make.conf because anything that breaks with -O3 doesn't use it because it is stripped out. But yes it is possible to do this without screwing you system up.

edit your make.conf to your changes that you want..

then

emerge -e system
emerge -e system
emerge -e world
emerge -e world

THIS will ensure everything on your system is compiled with the new GCC and new make.conf stuff and all the linked libaries that was used to compile those software are equally updated.

Anything less and you are potentially entruing a world of pain

Do have to change my kernel .config to pentium-m=y before all that stuff or can I do it afterwards?

[Naib]

final step after those 4 empty tree merges will be to recompile the kernel to ensure that it is also useing the latest GCC (and linked libaires) so last thing before a reboot

Got another Problem:

[Naib]

Back in the day
Sysvinit and baslayout were combined.
Then they were separate (looks like thats where you are)
They then re-combind them

unmerge sysvinit and try again.

IF it is really neede dit will get pulled in again, but it shouldn't be, prolly just a leftover package

Now I have a little problem with compiling arts-3.4.0:
I get this message:

[Naib]

This looks like one of the libaries that ARTS links against is not compiled with the correct GCC (hence the reason you have to do all those emerged to ensure everything is updated)

did you do
emerge -e system
emerge -e system

first.
ARTS is part of KDE and should not be done during the SYSTEM update stage.
IF it is getting pulled in via "emerge -e system" then I would recomend editing your make.conf file and disable X,and KDE stuff, then when hte 2nd "emerge -e system" is finished re-enable them and do the two "emerge -e world"

The two times emerege -e world worked without trouble but now I still get the Error when I try to emerge arts.

Wait, so are all of these emerge commands virtually the same as hootstrapping? Because I was expecting the usage of bootstap.sh

I've tried too hard... now the whole System is down. F**** Arts !! But I'm on the way to a real fast and save Stage 1on a Stage 3 Tarball installation. It looks very good...

I've finish installing. It's amazing how fast some Apps open, but this might be imagination. But I can advise this kind of installation, Thanks to the Jackass-Projekt!!!
