My profile has been ../usr/portage/profiles/default/linux/x86/2008.0 starting an update system today I'm told my profile is depricated and to update to default/linux/x86/10.0
I've forgotten about how this is done. Is it just a matter of ln -sf /usr/portage/profiles/default/linux/x86/10.0 /etc/make.profile ? Or does it involve something like a major regrind of every package? A quick google with site:gentoo.org "change profile" shows dozens of hits in forum messages, but I didn't notice a HOWTO or concise walk-thru.
