I just tried this out and while the initial file sync using unison seems to work, at some point, subsequent ones start to fail due to a lost connection with the server
error:

Any idea what's causing that? The container still seems to be running:
brikis98-pro:foo brikis98$ docker ps -a

I've also seen some similar errors, and I think it's related to the unison being unable to write to the file.

Perhaps, unrelated, but could this be the issue?

This seems to happen to me fairly often. I exported the container and inspected the log:

Seems to be related to:
http://www.spotwise.com/2015/01/06/broken-unison-brew-on-yosemite/
TLDR;
brew uses ocaml 4.02 while the ubuntu package manager provides 4.01. The error is caused by these mismatched versions.
