Docs for "OperatingSystemKind" condition?

[rmunn]

In #1042, @mlorbetske gives a sample post-action with "condition": "(OS != \"windows\")" so that it will only run on non-Windows systems. But in SAFE-Stack/SAFE-template#36, it seems that that condition doesn't actually work to exclude a post-action from a Windows machine, causing the template installation to fail. (That particular post-action runs the Unix chmod command, so it will only work on Linux or OS X machines). I've found one reference to a condition called OperatingSystemKind, but I haven't found any documentation for that condition. What values is it expected to have? How should I use it to ensure that a particular post-action only runs on Unix-like systems?

I believe the conditioning for "Windows or not" needs a value of Windows_NT (the value of the OS environment variable since Windows 2000/XP)

Yep, changing the condition to "(OS != \"Windows_NT\")" fixed SAFE-Stack/SAFE-template#36. And on further research, I found that the OperatingSystemKind variable I was asking about was a config variable set up just for those specific unit tests, and is not something generally available. So OS is the environment variable to check.

And this issue can be closed: now that I know how to check for Windows properly, I've updated the documentation for the chmod post-action to have the right condition, so there's no further action needed on this AFAICT.
