Hot code-reloading deploys error out during upgrades

[HashNuke]

An issue related to exrm or relx causes creating releases to error out. I've reported the issue here - bitwalker/exrm#167

Been updating details from debugging sessions and identified the problem.

i wonder if the solution to this is to simply run the app from another directory, as the exrm doc suggests. would you accept a PR that adds a /srv/app/{{ app_name}} directory and deploys the app there?

[HashNuke]

@manukall Yes. that would be wonderful. Right now the ansible scripts just start the release in the place it's built. The setup needs to follow the exrm docs instead and start the release after copying it elsewhere. By deploying to another directory (like /home/{{ deployer_user} }/srv/{{ app_name }} is a good place because all apps are under the non-root deployer user.

Haven't looked into this yet. I'll do it by this weekend.

@HashNuke I've followed the docs. And I get an error that some how I couldn't get past 😞

During this step

TASK: [HashNuke.elixir-stack | upgrade app] *********************************** 
<> ESTABLISH CONNECTION FOR USER: deployer

I get this error

stderr: fs: -c: line 0: syntax error near unexpected token `newline'
fs: -c: line 0: `rel/myapp/bin/myapp upgrade ==>'

I tried upgrading the exrm release manually and it works. Seems to be a problem with shell script? It would be great you could help 👍

Hot-code reloading is broken AFAIK.
I'll have to update it this weekend.

I've followed the docs and the versions are different, some how I
couldn't get past this. I tried upgrading the exrm release manually and
it works. Seems to be a problem with shell script? It would be great you I

I would like to experiment with hot upgrade, so a fix would be welcome.

@pinx being worked upon in another branch. Here's the status #23. Hopefully will be over by this weekend.
