Possible enhancement: Create timestamped deploy directories & symlink "current"

[pmeinhardt]

Upfront: I don't think this is a high-priority feature, but I thought I'd write down the idea here to maybe get the ball rolling 🙂👟⚽️

When deploying with Capistrano, you usually get timestamped release directories for every deploy and the current, used one, is just a symlink to one of them:

http://capistranorb.com/documentation/getting-started/structure/

├── current -> /var/www/my_app_name/releases/20150120114500/
├── releases
│   ├── 20150080072500
│   ├── 20150090083000
│   ├── 20150100093500
│   ├── 20150110104000
│   └── 20150120114500
├── repo
│   └── <VCS related data>
├── revisions.log
└── shared
    └── <linked_files and linked_dirs>

This could be interesting for archival purposes as a first step so you have a trail of previously deployed releases to go back to. Later on it could allow for something like a mix bootleg.rollback <env> if desired. This would be useful to allow for quickly going back to a previous version if something's wrong with the last deployed release.

The revisions.log and repo will likely look differently (or not be available at all) as the build & app server are separate and in the end we only deploy a built release (which doesn't include a revision).

Like I wrote, not a high-prio feature right now, but maybe nice as a future extension to bootleg 👋
