Running salt-master with rancher-nfs

Using Environment scoped rancher-nfs volumes
Tested with driver: local and problems does not happen

Is anyone using salt-master in rancher? If so did you have to do any special config on storage or other docker settings to get it to work properly?
I am trying to get salt-master to run in rancher, using environment volumes and rancher-nfs. When I do not run in privileged mode I will see warnings about ‘dmidecode’ installed but can’t be called by the user. Running in privileged mode got rid of all errors except when I try to run a custom state file with “salt ‘*’ state.sls apache” I get the error shown below. This page explains it to be an NFS related issue:
[salt.master ][ERROR ][30] Error in function _file_hash:

Well, I solved it by just not volume mounting the /var/cache/salt folder. Not necessary to persist that data anyways…
