Current behavior

$ mix nerves.release.init
** (Mix) Could not invoke task "release.init": 1 error found!
--template : Unknown option

Expected behavior

It should work as before. I just upgraded nerves_bootstrap to 1.6.0.

nerves.release.init is only required when initializing distillery releases. If you are generating a new project using Elixir 1.9 you do not need to call this command.

[milmazz]

@mobileoverlord I understand that for new projects nerves already provides a rel/vm.args.eex, which is suitable for releases with Elixir 1.9. But, if nerves plan is to forward the call from nerves.release.init to release.init that will fail for distillery >= 2.1.0 (on that version distillery introduced a breaking change), from now on the correct call to distillery is mix distillery.init --template foo.

Also, it would be helpful to mention on the Getting Started guide, that mix nerves.release.init is no longer needed if you don't plan to use distillery in your workflow.

[mobileoverlord]

Ah, I see what you are saying. I updated that PR to fix the forward call to distillery.release.init and also removed the bit in the getting started guides about the release configuration initialization. The getting started guides should be recommending people install elixir 1.9.0 and the new project generator will expand the new config into the mix.exs file.

@mobileoverlord That was fast! :) Thanks

This is fixed in 1.5.1
