To begin a simple upgrade, OSTree fetches the contents of the ref from
the remote server. Suppose we're tracking a ref named
`exampleos/buildmaster/x86_64-runtime`. OSTree fetches the URL
-`http://example.com/repo/refs/exampleos/buildmaster/x86_64-runtime`,
+`http://example.com/repo/refs/heads/exampleos/buildmaster/x86_64-runtime`,
which contains a SHA256 checksum. This determines the tree to deploy,
and `/etc` will be merged from currently booted tree.
