here i define _UNIXCONFDIR because test_platform import it variable, and if os-release directory will be defined in function, test_platform finished with error.

Wouldn't be better to search the 'os-release' file in the _UNIXCONFDIR directory similarly to searching other config files?

If search os-release file using an existing method, it is necessary to make a lot of changes to it, since the os-release file after sorting is in the last places and therefore it is not using in the future. I think that can find, if not, then look for the rest of the files. Now I have remade the commit in accordance with your remarks.

Why not just re.search() if you use only the first found match? What if the patter will be not found in the file?
The pattern r'NAME=.*' gives false positive for e.g. VERSION_CODENAME=.

what replaced linux_distribution? |

In some linux distributions, the information about the distribution is incorrectly determined when the linux_distribution() method is called from the platform class. Since the information file os-release becomes a certain standard, I propose first of all to check its availability and if it is in the system, then parse the information from it. I apply the patch. It will work well with version 2.7.
