Login as root and execute the following to switch a stoney cloud installation from stable (releases) to testing (pre-releases). If you are migrating from a FOSS-Cloud (or have an early stoney cloud), please read below and skip this step here.
branch="1.2-pre" cd /usr/portage git remote set-branches --add origin "${branch}" git pull --rebase git checkout "${branch}" chown -R portage\: . cd /var/lib/layman/foss-cloud git remote set-branches --add origin "${branch}" git pull --rebase git checkout "${branch}" chown -R portage\: .
Migrating from FOSS-Cloud
When coming from FOSS-Cloud or an early stoney cloud, it is necessary to switch the portage and portage-overlay to point to stoney cloud. To figure out, whether this is your case execute the following:
cd /usr/portage git remote -v
which should give the following if you are on FOSS-Cloud (or have an early stone cloud)
origin https://github.com/FOSS-Cloud/portage.git (fetch) origin https://github.com/FOSS-Cloud/portage.git (push)
cd /var/lib/layman/foss-cloud git remote -v
which should give the following if you are on FOSS-Cloud (or have an early stone cloud)
origin https://github.com/FOSS-Cloud/portage-overlay.git (fetch) origin https://github.com/FOSS-Cloud/portage-overlay.git (push)
If the output matches, run the following instead of the commands above to directly switch from whatever FOSS-Cloud/stoney cloud you have to a testing (pre-releases) stoney cloud:
rm -rf /usr/portage/* /usr/portage/.git /var/lib/layman/foss-cloud/* /var/lib/layman/foss-cloud/.git cd /usr/portage git init git remote add -t "1.2-pre" origin "https://github.com/stepping-stone/portage.git" git checkout --orphan "1.2-pre" cat >> .git/config << EOF [branch "1.2-pre"] remote = origin merge = refs/heads/1.2-pre EOF chown -R portage\: . cd /var/lib/layman/foss-cloud git init git remote add -t "1.2-pre" origin "https://github.com/stepping-stone/portage-overlay.git" git checkout --orphan "1.2-pre" cat >> .git/config << EOF [branch "1.2-pre"] remote = origin merge = refs/heads/1.2-pre EOF chown -R portage\: .
If using binary packages, you have to update the mirror configuration in /etc/portage/make.conf as well, as described in stoney cloud: Upgrade
