RE: [cdt-dev] First gotcha with add/exclude children of FFS

I guess my concern over team support is that it won't work with the EFS solution either. I'll need to investigate a bit more to see what the root issue is.

Doug,

I discussed this with Warren and Ed today and we remain skeptical that linked resources will be a viable solution, mostly because of the team support bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=41929  P5 RESOLVED LATER

On the other hand Ed pointed out that my question was probing in the wrong direction, a better solution would be to have an EFS representation of the actual project structure. In our case we already have some files that describe the contents of the project. Warren is going to investigate using these to populate an EFS file system. If that works we'll see if it is something we can generalize for CDT.

- Ken
