Comment 5 for bug 1385339

From email thread some time back:

After some discussion with Steve and others, I am thinking we may be fine with things as they are for the ubuntu and device images. We avoid the idea of dot releases, the current "parts" are already version with the date they were created, and the baseline Ubuntu distro version is also available. i.e. we currently have

OS Ubuntu 14.10 (r169)

Build number 169
Ubuntu image part 20141121.1
Device image part 20141119-db417fa (suffix is the git hash which to me is a bit obtuse)
Customization image part 1416428357 (no idea what this represents)
