@robinst is correct.
In git, you can select which branch is checked out by default (i.e. when you clone). By default, origin/HEAD
will point at that.
On GitHub, You can change this in the Admin settings for your GitHub repo. You can also do it from the command-line via
git remote set-head origin trunk
or delete it altogether via
git remote set-head origin -d
Example. Look at the ‘Switch Branches’ drop-down. trunk
is checked, so origin/HEAD
follows trunk
.
