   quite possibly.

[this](https://github.com/kubernetes/minikube/issues/229) (in vm rkt user is 
used while in the container we have user 185, but 185 cant write to that 
mounted folder in the vm because only the user on the host machine can write to 
it by default). But there is a workaround set `--gid` and `--uid` and 
`--9p-version=9p2000.L`. Hopefully I will be able shortly to report back here a 
fully working example and maybe we can reproduce it on the test nodes 
   
   yeah, even if i run a separate `minikube mount` w/the gid and uid options, i 
still can't get things to work properly.  i can log in to the pod, see the 
mount, and touch files, create dirs, etc, but the integration tests STILL fail 
on the java `Mkdirs()` call.

   now *that's* an understatement.  ;)
