Yes, but I take that with a pinch of salt because there's no Windows API
call that performs a real fork. There are similar functions to spawn()
but nothing that does CoW like fork().
Microsoft had an experimental Windows port of Redis a year or so ago and
that was the issue that made it not production ready.

Indeed, my mistake. They intercept syscalls and translate them to
Windows API calls. It's like a giant kernel shim. I wonder how to handle
fork()? Windows doesn't support forking which is significant if you want
to run popular open source software like redis.
When Richard Stallman learns of this I imagine he will have a bit to say about
the terminology. (https://en.wikipedia.org/wiki/GNU/Linux_naming_controversy)
It seems to me that this is really GNU user code running on Windows, not Linux
on Windows, since they specifically say there is no Linux kernel code present,
and Linux really is only the kernel.

Microsoft are partnering with Canonical. The Linux subsystem is
effectively and Ubuntu distro without the kernel. Good on them. I've
been running headless linux VM guests under VirtualBox but this much
better as it's integrated.

I run Git for Windows on my work PC which is very good indeed. It has a
bash shell emulator and a nice GUI. We use SMB on z/OS and map the
network drives on windows, so it's easy to use git from the command line
with the working directory mapping to the zFS file system. It's simple
to push/pull stuff from/to github. We have a private github account and
it's a great platform for development. We use the issue tracking system
to create a backlog of work items. The tooling on github is superb.
I've recently been using a beta version of Windows 10 that has an
integrated Ubuntu Linux VM running so I can use bash natively
https://msdn.microsoft.com/en-us/commandline/wsl/about. It's great, much

better than VirtualBox running VMs or Cygwin. It's a smart move by
Microsoft. All the young kids are working on open source these days and
they all uses macs because of the toolset, bash, homebrew etc. By
integrating a Linux subsystem into Windows they may attract hipster
hackers back the platform. Desktop Linux is ok but it's nowhere near as
polished as iOS or Windows.

Can you clarify? Do you run 'git' on Windows (I assume) and specify SMB
folders that actually exist on USS as your local repository (or whatever its

Sounds interesting. Of course we don't use z/OS SMB, so that's an, umm,
"opportunity". :-)

Sidetracking, has anyone used GitHub for z/OS production source
repository. Meaning interacting with it directly from the mainframe? All
of our distributed development groups use it, and it might be nice if we
could use it as well.
Just as a personal observation, I'd think that this would be difficult.
Someone would need to port the "git" command to z/OS. And that would likely
be a major undertaking since it uses the GNU tools to do a lot of it's
setup. It may also depend on some gcc (GNU compiler) specific
functionality. And, even if it is ported, there is the historic ASCII (UTF
actually) vs EBCDIC dilemma. You wouldn't believe the number of problems
I've read about due to the Windows CRLF vs UNIX LF-only line ending causing
"problems".
I use git for z/OS UNIX stuff via SMB and it works well from a PC shell.
A script that mirrors PDS libraries should work.
