Comment 1 for bug 904633

I hacked around with the schdiff file and found that /tmp was not the real problem. Instead, it turns out that git does not respect the cwd (search for this on the web). It moves it's cwd to the top of the git tree and then opens the schematics form that cwd. The schematics files can be in /tmp.

If you make links to your gafrc and any local symbol directory at the top of the git tree, then it should work. Worked for me.

There might be a better solution using git...
