Hello,

Is there a way to specify a branch in repos.conf/overlay_name.conf?

[rage]
location = /usr/local/portage/rage
sync-type = git
sync-uri = https://github.com/lramage94/overlay.git^feature/beta-packages
priority=9999
EOF

Something like this?

Thanks

The source of Portage's pym/portage/sync/modules/git/git.py contains
this comment:
def update(self):
        ''' Update existing git repository, and ignore the syncuri. We are
        going to trust the user and assume that the user is in the branch
        that he/she wants updated. We'll let the user manage branches with
        git directly.
        '''

To that end, I think the answer is no.

If this were to change, there are a bunch of questions that would need agreement in how they are answered:
- if the repo's remote URI has changed, should we update the git checkout's
  remote URI from sync-uri? (what if there are multiple remotes in the checkout?)
- if the repo's branch has changed in the config, should we update the checkout's branch?

I answered the initial question off-list, copying the list this time.
It's actually it's possible.

    sync-git-clone-extra-opts  = -b branchname

will clone only single branch and will create a shallow clone.
all the future  syncs will pull this branch as explained above in the source 
code snippet.
