Re: Re: git clone doesn't work in symlink dir roots on Windows

[Michael Geddes <michael@frog.wheelycreek.net>]

This type of functionality is directly supported by the work I've already done 
on symlinks here:   https://github.com/frogonwheels/git   
(branches mrg/symlink-v*  )

Even if we agree that symlinks only work to a limited degree, or that there 
are definite limitations, and that the default should be that symlinks NOT be 
supported within repositories, I'm not sure why people are against 
incorporating what I've already implemented.. ok well I guess I do - it's 
about time.

Firstly, at the least it means that symlinks like this example where they are  
outside the repository are supported.  Secondly it means that people who are 
prepared to accept the limitations will be able to use (or at least clone) 
repositories containing symlinks.

One of the big, painful limitations is that windoze symlinks need to be marked 
as directories at the time of creation.  The code I have implemented does it's 
level best to create the correct type of NTFS symlink based on repository 
information and falling back on filesystem information.

The argument about permissions is only partially valid, since that can be 
granted as an individual permission to the user without permanent 
administrator rights.
