Of course this would only make sense if the > symlinks resolve to something that is tracked :) Last April, I was working on making archive follow all symlinks pointing to internal files. The goal was a bit different, namely to create archives for platforms without symlink support (i.e. it would resolve all symlinks pointing to tracked objects). IIRC the code had some limitations, e.g. it couldn't follow a symlink to a path containing symlinked directories. I'll need to rebase it to master first, though, as the surrounding code has changed a bit in the meantime. To follow only symlinks that point outside of the specified paths sounds like a sensible mode of operation, but I'm not sure that it's worth a one letter option. Given your setup you also might want to take a look at submodules and the recent submodule archival support patches by Lars Hjelmi. Anyway, I'll try to resurrect my old, incomplete symlink following code, but I don't have much time, either. :-/ René -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
