------------------------------------------------------------------
New patch, addressing [~janhoy] comments.
The patch needs refguide docs.
- done
Should it also be documented in bin/solr -h?
- done
Should "/solr" be an always-whitelisted path?
- Not useful if -DcreateZkRoot=true, because any path will be ceated
Nipick: Consider terminology - is it zkRoot or zkChRoot?
- Keeping 'createZkRoot' in the new patch. It at least avoids changing scripts
on our side ;)
- I'm not a fan of "chroot". Doesn't 'ch' mean "change" ? So "createZKChRoot"
would mean "create the zookeeper change root" ?
- It could be createZkNode ? createZkPath ?
I can't find the test class TestZkChroot.java in master branch, so, no unit
test this time.

> 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?
