Using the Funtoo experimental branch is considered experimental (unsupported). Users should be prepared to have various package compilation errors or other problems.
The Funtoo experimental branch is used by Funtoo Core Developers to try and test new features to be included in Funtoo stable and current branches when ready. Users that want to help the developers test those new features are welcome to switch to the experimental branch and report problems on IRC or the forum. However, problems may arise from using it and there is no guarantee that your system will stay usable.
For now, the experimental branch is the same as the current branch. It has been used recently to implement and stabilize a new set of toolchain packages, but those changes have been recently merged into the Current branch and we are waiting for new stuff to test.
Upgrading an existing Funtoo installation to experimental
# rm -rf /usr/portage # nano -w /etc/make.conf
Add the following line (or modify it if it's already there):
# emerge --sync
Verify that the experimental tree has been properly installed:
# cat /usr/portage/.git/config ... [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = git://github.com/funtoo/experimental-mini-2011.git ...
You should see that the git repository is pointing to experimental-mini-2011.git.
If for any reason this method did not work, use the second method to manually clone the experimental branch.
# rm -rf /usr/portage # cd /usr # git clone git://github.com/funtoo/experimental-mini-2011.git portage # emerge --sync
Installation from an experimental branch stage3
You can find some stage3s on the Funtoo mirror: . However, those stages will not be updated very often.
