* In MOS8 system user `nova` has different uid/git on compute nodes.
During deployment on each compute node puppet changes permissions
for NFS mount point. As result only one node (the one which has been
deployed last) can use NFS share. All other nodes faice permission
errors.
* parseyaml() function deprecated, use hiera instead
