Random string in data path breaks application

[tzu]

In the last stable version of Snappy Ubuntu we have a random string in /var/lib/apps/foo/ instead of numeric version of our application. This feature prevents access to the data for binaries with built-in paths. For example, we have a project that uses recompiled lxc binaries to manage containers with rootfs located at /var/lib/apps/foo/0.0.1/containers/bar. With random string at this path we cannot access containers data.

we plan to start auto assigning revisions in store; this means that the ability to guess the path during build time will go away anyway. Best would be to make software relocatable, but stgraber mentioned that for LXC this is not an option for security reasons.

On IRC it was discussed that a current link for APP_DATA_PATH might work if it fits in our vision.

Needs discussion with team..

I believe this is addressed with having a "current" in APP_DATA_PATH, which we now do.

changed to fix committed as this is in rolling but not 15.04 yet.
