wclayer create fails on multiple parent layers

[liangyuRain]

I was trying to create a writable scratch layer based on two read-only layers from microsoft/nanoserver:latest. After I imported the two layers, when I tried to run .\wclayer.exe create -l l_1 -l l_2 l_3 (l_1 and l_2 are the read-only layers, l_3 is the scratch layer I want to create), it failed with:

ERRO[0000] hcsshim::CreateScratchLayer failed in Win32: The system cannot find the path specified. (0x3) path=C:\Users\t-liazha\Desktop\test\l_3
hcsshim::CreateScratchLayer failed in Win32: The system cannot find the path specified. (0x3) path=C:\Users\t-liazha\Desktop\test\l_3

Any one has any idea on this?

It turns out that the order of the paths to parent layers is causing the problem. For .\wclayer.exe create, the last layer should be the base layer. In our case, the command should be .\wclayer.exe create -l l_2 -l l_1 l_3.
