Upgrading Gentoo 2007.0 to 10.0

отсюда http://allmybrain.com/2009/11/10/upgrading-gentoo-2007-0-to-10-0/
So I left all these servers running gentoo a couple years ago. Now, after all this time (and uptime!), I want to install something.

Error:

emerge -av portage

These are the packages that would be merged, in order:

Hm. Yeah, I’m way out of date.

Solution: I found other sites that talked about forcing a python/portage install but I that sounded a little harsh. Instead, I found a snapshot of portage-2008.0 and replaced my /usr/portage with the contents of that.

cd /usr
rm -rf portage # or mv portage xxx
wget http://gentoo.mirrors.tds.net/gentoo/releases/snapshots/2008.0/portage-2008.0.tar.bz2
tar -xjpf portage-2008.0.tar.bz2
cd /etc/
rm make.profile
ln -s /usr/portage/profiles/default/linux/x86/2008.0 make.profile
emerge -av portage

That took me to portage-2.1.4.4.

From there, I can now go back to current 10.0 portage and emerge -av portage to get up to the current portage state.

Yeah, I really didn’t want to do a re-install.
