WSL install, permission denied for fusesoc.conf, saved to current directory

[gojimmypi]

This appears to be a relative path, or perhaps even path case problem.

Yes, please don't leave the room screaming when reading about case sensitivity. lol ;)

The default directory for WSL is /mnt/c/Windows/System32 when first launching WSL on Windows 10.

When running fusesoc library add from the default directory, an error is encountered:

The problem seems to be when processing arguments to determine the path for the config.

Note my local main.py file line 216 is actually on line 217 of the source for the config = Config(path="fusesoc.conf")

I think the problem is here in the config.py

As at that point, path just contains the text fusesoc.conf, with no path, which also explains the error: I would fully expect things to not be able to write to the Windows system32 directory.

And sure enough, looking in my home directory, there's a new fusesoc.conf file. Is that where it should be?

Probably not, as the FuseSoc Quick start clearly states to create a new directory, but not as clearly indicated in the serv prerequisites, which is where I started.

I created #69 and olofk/fusesoc#536 to help clarify for future new users.
