Maybe look for synthetic firmlinks in the root directory and use that information to figure out what aliases there might be to the worktree. lrwxr-xr-x 1 root wheel 30 Sep 2 11:52 mathworks -> /System/Volumes/Data/mathworks If what the link resolves to is a prefix of the worktree, then it is a firmlink to the worktree. Something like that. -Eric
