Gentoo Upgrading your Profile

At some point, I need to upgrade my Gentoo profile from 2004.3 to 2005.0. Here's the error message that you see on screen when you need to do this.

livecd linux # emerge (something)

!!! Your current profile is deprecated and not supported anymore.
!!! Please upgrade to the following profile if possible:
default-linux/x86/2005.0

To upgrade do the following steps:
# emerge -n '>=sys-apps/portage-2.0.51'
# cd /etc/
# rm make.profile
# ln -s ../usr/portage/profiles/default-linux/x86/2005.0 make.profile

# Gentoo has switched to 2.6 as the defaults for headers/kernels. If you wish
# to use 2.4 headers/kernels, then you should do the following to upgrade:
# emerge -n '>=sys-apps/portage-2.0.51'
# cd /etc/
# rm make.profile
# ln -s ../usr/portage/profiles/default-linux/x86/2005.0/2.4 make.profile
