[gentoo-dev] [Fwd: Re: [gentoo-user] Old HW gentoo installs]

Hello All

I think this is the question for you, not for gentoo-user mailing-list.

The main question is
how to make binnary .tbz2 packages for target
with incompatible instruction set,
for example, on Pentium4 for ViaC3

Hello All

I think Gentoo is the best linux distr. But it has the big flaw.
It is not optimized for offline users (it can be easy done, I'm offline 
user),
and not for slow computers, old notebooks, etc.

The first step is done.User can add
'PORTAGE_BINHOST=' to make.conf
and use binnary packages
but how to setup 'fast server' to create .tbz2 packages?

ok

I can chroot from pentium4 to pentium2 and fast compile all packages,
good, what about chroot from AthlonXP or from Pentium4 to ViaC3 ???

This is the main question:
How to make binnary packages (tbz2 's) no AthlonXP optimized for Via C3?
(what way is for machines with imcompatible instruction set)
if I want to use optimized system I need to start from stage1,
and not use stage2 or stage3...

The dreams:
on Athlon XP
-download and unpack to separate dir stage1 and last portage snapshot
-may be mount --bind dev and proc and chroot
-change profile via symlink
-edit make.conf (CFLAGS="-march=c3 -O3 -pipe" FEATURES="buildpkg")
some-other-bootstrap.sh
emerge system
emerge --buildpkg  windowmaker , emerge --buildpkg mozilla and emerge 
--buildpkg some-package again
export or copy all .tbz2 packages to ViaC3 hosts
install .tbz2 packages by emerge --usepkgonly package-name on ViaC3

Thanks for any ideas.
