Standard Grains aren't very standard

[erenfro]

There are some grains in certain distros, different grains in others. These should be standard accross them all since they're salt-generated grains.

Example:

CentOS has osmajorrelease, while Debian and Ubuntu do not. This array is very helpful in determining major release checking.

Another example is osfinger exists in CentOS and Ubuntu which returns CentOS-6 for CentOS 6.4, and Ubuntu-12.04 in Ubuntu 12.04, but in Debian, no osfinger value at all but should be Debian-7 for Debian 7.x, or similar. Ubuntu might be better to base it on codename, rather than release version as well. such as Ubuntu-precise, since there is Ubuntu 12.04, 12.04.1, 12.04.2, etc..

Just some examples found of inconsistencies between standard salt-generated grains between a few distros supported by it.

Ya, a lot of these grains have been added haphazardly, and need to be normalized across the various distros. Thanks for filing this!

Still have this bug, using salt-minion 2014.1.11 (Hydrogen) (2014.1.11+ds-2~bpo70+1) on debian wheezy.
