Read-only File System Error when enabling for an app.

Description of problem

I am honestly not sure where in the stack this problem lies, but since this is the only command that is failing this is where I will start.

How reproducible

It is now happening for all my apps, including apps that have already been configured.

Steps to Reproduce

1. run dokku letsencrypt:enable reckless-embermine

Actual Results

jbosse@server:~$ dokku letsencrypt:enable reckless-embermine
