Just to let you know that the AMD64 packages indeed appear usable on the Windows 10 "thingy" (a.k.a. "Windows Subsystem for Linux (beta)" or better as "Microsoft-Windows-Subsystem-Linux" in powershell parlance - e.g. to install under elevated powershell run something like
Get-WindowsOptionalFeature -Online | ? {$_.FeatureName -like '*Linux'} | Enable-WindowsOptionalFeature -online
).
I was going to bootstrap one of these days pkgsrc under it, now I probably won't bother.
The PKG_PATH is a little different from the one in the mail message, though -
as well as the location of the bootstrap archive -
