[jreed]

The following patch will provide some details on an unknown system:

I understand that this may not work on non-Unix but we can handle that later.

I don't understand what the problem is. Could you be more specific?

From what I gather, the problem is that in case we don't have a specific subclass for the OS that it is run on, it shows nothing at all. The proposal is to at least print some info if we can get it (through python's os module).

commit 89fbc1a1f41da33150176d8d0ba83ae8e88a03da

I didn't make a changelog entry for this since it is still incomplete for unknown systems (see #2085) and this change is minor.

Closing this ticket.
