> If you launch Solr for the first time in cloud mode using a ZooKeeper connection string that includes a chroot leads to the following initialization error:

> The work-around for this is to use the scripts/cloud-scripts/zkcli.sh script to create the chroot znode (bootstrap action does this).
> I'm wondering if we shouldn't just create the znode if it doesn't exist? Or is that some violation of using a chroot?
